Read JSON from Facebook?

Hello Guys :) I have a game in which I want to pull the scores from the facebook of the user which has logged in.

This is my code - >

 public string Dialog;
 public static int FBhighScore;

 void Awake()
 {

 }

 // Use this for initialization
 void Start (){
     if(FB.IsLoggedIn){

         var PulledScore = new Dictionary<string,string>();
         PulledScore["score"] = FBhighScore.ToString();

         gameObject.GetComponent<Text>().text = Dialog+FBhighScore;
         FB.API ("/me/scores",HttpMethod.GET, delegate(IGraphResult result) {
             print ("Pulled Score Result : "+ result.RawResult);
         }, PulledScore);


     }
 }

It gives the JSON data that comes from the facebook. This is it - >

{"data":[{"score":85,"user":{"name":"Mary Alabfabbdghgi Okelolawitz","id":"109442539486154"}}]}

I want to show the score of this person to a UI Text element.

How can I get it done?

Please help :)

Thanks Regards, Manu
