Leaderboard GUISkin?

Hey guys, I need some help getting my leaderboard to match with the theme of my game, at the moment I have the leaderboard working correctly, and appearing, but not with my GUI skin, it's only the default, here's what I have so far:

 using UnityEngine;
 using System.Collections.Generic;
  
 public class LeaderBoardSample : MonoBehaviour {
     float startTime = 10.0f;
     float timeLeft = 0.0f;
  
     public GUISkin guiSkin;
  
     Rect windowRect = new Rect (0, 0, 620, 520);
  
     string playerName = "";
     string code = "";
  
     enum gameState {
        waiting,
        running,
        enterscore,
        leaderboard
     };
  
     gameState gs;
  
  
     // Reference to the dreamloLeaderboard prefab in the scene
  
     dreamloLeaderBoard dl;
     dreamloPromoCode pc;
  
     void Start () 
     {
        // get the reference here...
        this.dl = dreamloLeaderBoard.GetSceneDreamloLeaderboard();
  
        // get the other reference here
        this.pc = dreamloPromoCode.GetSceneDreamloPromoCode();
  
        this.timeLeft = startTime;
        this.gs = gameState.waiting;
     }
  
     void Update () 
     {
        if (this.gs == gameState.running)
          {
           this.gs = gameState.enterscore;
        }
     }
  
     void OnGUI()
     {
  
        GUI.skin = guiSkin;
  
        GUILayoutOption[] width200 = new GUILayoutOption[] {GUILayout.Width(200)};
  
        float width = 400;  // Make this wider to add more columns
        float height = 200;
  
        Rect r = new Rect((Screen.width / 2) - (width / 2), (Screen.height / 2) - (height), width, height);
        GUILayout.BeginArea(r, new GUIStyle("box"));
  
        GUILayout.BeginVertical();
        if (this.gs == gameState.waiting || this.gs == gameState.running)
        {
           this.gs = gameState.running;
  
          GUILayout.Label("Total Score: " + GameLogicScript.score);
        }
  
  
  
        if (this.gs == gameState.enterscore)
        {
          GUILayout.Label("Total Score: " + GameLogicScript.score);
          GUILayout.BeginHorizontal();
          GUILayout.Label("Your Name: ");
          this.playerName = GUILayout.TextField(this.playerName, width200);
  
          if (GUILayout.Button("Save Score"))
          {
           // add the score...
           if (dl.publicCode == "") Debug.LogError("You forgot to set the publicCode variable");
           if (dl.privateCode == "") Debug.LogError("You forgot to set the privateCode variable");
  
           dl.AddScore(this.playerName, GameLogicScript.score);
  
           this.gs = gameState.leaderboard;
          }
          GUILayout.EndHorizontal();
        }
  
        if (this.gs == gameState.leaderboard)
        {
          GUILayout.Label("High Scores:");
          List<dreamloLeaderBoard.Score> scoreList = dl.ToListHighToLow();
  
          if (scoreList == null) 
          {
           GUILayout.Label("(loading...)");
          } 
          else 
          {
           int maxToDisplay = 20;
           int count = 0;
           foreach (dreamloLeaderBoard.Score currentScore in scoreList)
           {
               count++;
               GUILayout.BeginHorizontal();
               GUILayout.Label(currentScore.playerName, width200);
               GUILayout.Label(currentScore.score.ToString(), width200);
               GUILayout.EndHorizontal();
  
               if (count >= maxToDisplay) break;
           }
          }
        }
        GUILayout.EndVertical();
        GUILayout.EndArea();
     }
  
  
 }

I essentially need to present these kind of like the code bellow, where the code above replaces my buttons bellow:

 using UnityEngine; 
 using System.Collections;
 
 public class GameOver : MonoBehaviour {
 
 public GUISkin guiSkin;
  
 Rect windowRect = new Rect (0, 0, 620, 520);
 private bool toggleTxt = false;
 string stringToEdit = "Text Label";
 float hSliderValue = 0.0f;
 float vSliderValue = 0.0f;
 private float hSbarValuet;
 private float vSbarValue;
 private Vector2 scrollPosition = Vector2.zero;
  
  
 void  Start (){
  
     Time.timeScale = 1.0f;
     Screen.sleepTimeout = SleepTimeout.NeverSleep;
     windowRect.x = (Screen.width - windowRect.width)/2;
     windowRect.y = (Screen.height - windowRect.height)/2;
 }
  
  
 void  OnGUI (){
     GUI.skin = guiSkin;
  
     windowRect = GUI.Window (0, windowRect, DoMyWindow, "Game Over");
  
  
 }
  
  
  
 void  DoMyWindow ( int windowID  ){
  
     GUI.Button (new Rect (140, 50, 340, 50), "Score: " + GameLogicScript.score);
     if (GUI.Button (new Rect (140, 120, 340, 50), "Post Score"))
        Application.LoadLevel ("Post Score");
     if (GUI.Button ( new Rect(140,190,340,50), "Restart"))
         Application.LoadLevel ("TestScene1");
     if (GUI.Button ( new Rect(140,260,340,50), "Main Menu"))
        Application.LoadLevel ("Menu");
     if (GUI.Button ( new Rect(140,330,340,50), "Quit"))
        Application.Quit ();
 }
 }

I hope I made that clear, thanks in advanced!
