high score script?

Hello. This is the script for the scores in my game. It uses the currently selected combination of options to set a unique integer, so that each combination has its own high score.

    function Update () 
    { var Arcade : String = System.String.Format("{0}{1}{2}_score", Arcade.ModeInt, Arcade.DifficultyInt, Arcade.CharacterInt);
        PlayerPrefs.SetInt(Arcade, Stats.Score);
 }

How would I combine it with this script from the wiki(array prefs)? I want to be able to store more than one score for each option combination so I can have a high score table. Thanks.

var myScores = new int[10];
for (i = 0; i < myScores.Length; i++)
    myScores[i] = i+1;
if (!PlayerPrefsX.SetIntArray("Scores", myScores))
    print("Can't save scores");
