I don’t think using NSScrollView is at all necessary in this case. That’s much more of a situation for user interaction.
This sounds more like the case for creating a view subclass that contains a view that displays the current score. When the score increases, insert another view visually above the other ( so it’d be like Main View ———— New View then using an animation proxy to move the main view up and the new view up as well.
