Score script problems

I got this script from activeden.net but I have no idea on how to to make it give me more than 1 score? can someone please just take a look and tell me what I need to change so it can give me more than 1 score?

Score Script Here

There is a line which reads

score++;

instead replace that entire function with:

function scoreMany (points : int)
{
    score += points
}

then, when you are calling the score function, call it with

scoreMany(howeverManyPointsToScore);
