Sort a List with a public class

Hello I Have to sort a list with two properties playerName and score. Thanks in advice.

using System.Collections; using System.Collections.Generic; using UnityEngine; using System; public class ManageListLeaderboard : IComparable<ManageListLeaderboard> { public string playerName; public int score; %|1830307367_3|% %|-714131633_4|% score = newScore; } public int CompareTo (ManageListLeaderboard other) { if (other == null) { return 1; } return score - other.score; %|-212554372_13|% }

And this is the manage script of the level.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 using System;
 
 public class MultiplayerScript : Photon.MonoBehaviour {
 
     //---------------------------------------- SCORE PLAYERS ---------------------------------
 
     public Text [] scorePlayerText;
     public List<ManageListLeaderboard> manageLeaderboard;
     public Text[] LeaderBoardText;
     public int[] score;
     public GameObject leaderboardPanel;
 
     public bool call = false;
 
     //-----------------------------------------------------------------------------------------
 
     void Start(){
         
         manageLeaderboard = new List<ManageListLeaderboard> (); 
         score = new int[8]; 
     }
 
     void Update(){
 
         scorePlayerText [0].text = score [0].ToString ();
         scorePlayerText [1].text = score [1].ToString ();
         scorePlayerText [2].text = score [2].ToString ();
         scorePlayerText [3].text = score [3].ToString ();
         scorePlayerText [4].text = score [4].ToString ();
         scorePlayerText [5].text = score [5].ToString ();
         scorePlayerText [6].text = score [6].ToString ();
         scorePlayerText [7].text = score [7].ToString ();
 
         foreach (ManageListLeaderboard man in manageLeaderboard) {
 
             print (man.playerName + "   " + man.score);
 
         }

             manageLeaderboard.Add (new ManageListLeaderboard (PhotonNetwork.playerList [0].ToString (), 3));
             manageLeaderboard.Add (new ManageListLeaderboard (PhotonNetwork.playerList [1].ToString (), 5));
             manageLeaderboard.Add (new ManageListLeaderboard (PhotonNetwork.playerList [2].ToString (), 8));
             manageLeaderboard.Add (new ManageListLeaderboard (PhotonNetwork.playerList [3].ToString (), 7));
             manageLeaderboard.Add (new ManageListLeaderboard (PhotonNetwork.playerList [4].ToString (), score [4]));
             manageLeaderboard.Add (new ManageListLeaderboard (PhotonNetwork.playerList [5].ToString (), score [5]));
             manageLeaderboard.Add (new ManageListLeaderboard (PhotonNetwork.playerList [6].ToString (), score [6]));
             manageLeaderboard.Add (new ManageListLeaderboard (PhotonNetwork.playerList [7].ToString (), score [7]));
 
             manageLeaderboard.Sort ();
             manageLeaderboard.Reverse ();
         }
