When Tera gives you the prompt, type a number and she'll put it in the list. The numbers are placed highest to lowest. Type 'clear' and she'll remove all the numbers.
In case I ever made a game with a cloud data list, I'd have to make sure I knew how to sort highscores in order.

Except *not* from Scratch, because I didn't look inside another project to figure it out -- you know what I mean? [ba-dum Tss] ~~~ This is actually my 75th project! Hurrah!
