Use NSArray to keep the scores. And save/load it using NSUserDefaults

If you have a fixed number of levels - use NSArray to keep. When array values are changed:

-(void) saveScore
{
    NSUserDefaults *settings = [NSUserDefaults standartUserDefaults];
    [settings setObject: myScoreArray forKey:@"my scores"];
    [settings synchronize];
}

To load your array:

-(void) loadScores
{
    NSUserDefaults *settings = [NSUserDefaults standartUserDefaults];
    myScoreArray = [settings objectForKey:@"my scores"];
    //also check if myScoreArray in nil - first launch
}
