Since Perl doesn't make your declare your variables' type when you
create them, you need to tell it what kind of data you have when you use
the variable.
In this case, you're sorting lexically rather than numerically. Use a
sort function like:
@results = sort {$a <=> $b} @array; # an ascending numerical sort.
instead of:
@results = sort @array; # which is equal to sort {$a cmp $b} @array.
The difference is '<=>' (numerical comparison) against 'cmp' (lexical
comparison).
Hope this helps. perldoc -f sort for more information.

As to luck, there's the old miners' proverb: Gold is where you find it.
