Facebook API gives 403 Forbidden error when trying to post scores

I am trying to make a test aplication to implement as much functionality of the facebook API in unity. I am trying to post scores right now and it gives 403 Forbidden error. Searching on Google it says to check permissions which I have. And to make sure to make sure that the Game is tagged as a game on facebook. Did that too.

Login method:

 public void LoginToFacebook()
     {
         FB.Login("public_profile,email,user_friends,publish_actions,friends_games_activity,user_games_activity", LoginCallback);
     }

And post score method:

 public void postScore()
     {
         var query = new Dictionary<string, string>();
         query["score"] =  "" + 100;
         FB.API("me/scores", Facebook.HttpMethod.POST, delegate(FBResult r) { print (r.Error); }, query);
     }

Any help is apreciated.
