variables reset value

Hi all! I am making a old school pong game, and I am quite stuck now. i have made that when player01 scores 10 points, a new scene will show up, saying that this team has won. But if you return to the Main Menu by clicking a button, and play the game again, the score won't reset. Can someone please help me out? Here are the scripts I use:

//for the score

 #pragma strict
 
 static var playerScore01 : int = 0;
 static var playerScore02 : int = 0;
 
 var theSkin : GUISkin;
 
 var theBall : Transform;
 
 function Start () {
     theBall = GameObject.FindGameObjectWithTag ("Ball").transform;
 }
 
 static function Score (wallName : String) {
     if (wallName == "rightWall")
     {
         playerScore01 += 1;
     }
     else {
         playerScore02 += 1;
     }
         if (playerScore01 == 10) {
             Application.LoadLevel("OrangeWins");
             Debug.Log("OrangeWins");
         }
         if (playerScore02 == 10) {
             Application.LoadLevel("OrangeWins");
             Debug.Log("PurpleWins");
         
         }
         if (Application.LoadLevel == true) {
             playerScore01 = 0;
             playerScore02 = 0;
         }
     Debug.Log("Player Score 1 is" + playerScore01);
     Debug.Log("Player Score 2 is" + playerScore02);
     
         
         
 }
 
 function OnGUI () {
     GUI.skin = theSkin;
     GUI.Label ( new Rect (Screen.width/2-150-18, 20, 100, 100), "" + playerScore01);
     GUI.Label ( new Rect (Screen.width/2+150-18, 20, 100, 100), "" + playerScore02);
     
 //    if (GUI.Button ( new Rect (Screen.width/2-121/2, 35, 121, 53), "RESET")) {
 //        playerScore01 = 0;
 //        playerScore02 = 0;
         
 //        theBall.gameObject.SendMessage ("ResetBall");
 //    }
         
 }

     //move each wallto its edge location:
     topWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f ,0f)).x,1f);
     topWall.center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3 (0f, Screen.height, 0f)).y + 0.5f);

     }
     else {
