C# data saved in playerPrefs with Java menu

Just as messed up as the title sounds. I have a lovely javascript pause menu that i kept because it actually works when I SAVE the player transform and level. Something that C# likes to make a ridiculous pain. the pause menu also has many other functions that work so I do not want to make a C# version. Problem is, I want to add to the SAVE feature other variables of the player that are in C# scripts to PlayerPrefs. Namely the score, health. I am able to do so with key strokes. but that just seems dumb to have to do that in addition to a pause menu. I am trying to convert this save to java so I can then add it to the SAVE functionality in my pause menu. the attached script is how I save and load the players score to PlayerPrefs in C# using keystrokes. I guess I need a javascript that could access this scripts score variable. From that I could add it to my pause menu script. I have spent 2 days studying this online and just get the same errors about "converting a component into int." and others.

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class ScoreManager : MonoBehaviour
 {
     public static int score = 0;     
     public int MyScore;
     public int ReStart;
     Text text;                     
     
     
     void Awake ()
     {
 
         text = GetComponent <Text> ();
 
     }
     
     
     void Update ()
     {
         if (Input.GetKeyDown(KeyCode.S))
             PlayerPrefs.SetInt ("MyScore",score );
 
         if (Input.GetKeyDown(KeyCode.A))
             score = PlayerPrefs.GetInt ("MyScore" );
 
         text.text = "Score: " + score;
     }
 }
