Answer: How do I sort a list of numbers?

you need to use the numerical comparison operator <=> inside of your sort function

@sorted=sort{$a <=> $b} @unsorted;
If you did
@sorted=sort @unsorted;
the sort function defaults to doing a textual comparison so 375 would be considered less than 4 since its first character 3 is less than 4.

Here is a twist: How to sort an array of referenced hashes, based on a perticular key value.

@sorted=sort{$$a{key} <=> $$b{key}} @unsorted;

    [ambrus]: Corion: which coordinate system is the upside down one?
    [Corion]: ambrus: "the other" ;) To me, "normal" for GUIs means (0,0) is left-upper corner of the monitor/window. But for Prima, the lower-left corner it is ;)
    [Corion]: Which would be OK for mathematics and paper, for me ;)
    [ambrus]: Ok, so Prima has a postscript-like coordinate system
    [Corion]: ambrus: Yes, which kinda makes sense because Prima also has Postscript output or something, I think
