Data.cs

using UnityEngine;
using System.Collections;

public class Data  
{
	public readonly static Data Instance = new Data();

	public int score = 0;
	public string name = string.Empty;
}

LoadScene.cs

using UnityEngine;
using System.Collections;

// データをstaticに格納してシーンを呼ぶ側
public class LoadScene : MonoBehaviour 
{
	void Awake()
	{
		Data.Instance.score = 30;
		Data.Instance.name = "toppo";
	}

	// click callback
	public void OnClick()
	{
		Application.LoadLevel (1);
	}
}

ReadData.cs

using UnityEngine;
using System.Collections;

// 受け取る側
public class ReadData : MonoBehaviour 
{
	void Start () 
	{
		Debug.Log (Data.Instance.score);
		Debug.Log (Data.Instance.name);
	}
}
