No, it's quite clear that the score goes up to well above 1,000. Press "Score Test" without changing anything, and you'll get a score of around 900-1,100. Press the back button and do it again, and you'll get the same score. Press back, swap two adjacent colours, and you'll get a (usually) different but similar score.
Press reload and you'll get a different ordering with a different score.
