This may work:
my @pretty = sort
my @a = $a =~ /^(.+?)(\d*)$/;
my @b = $b =~ /^(.+?)(\d*)$/;
return ( $a cmp $b ) ||
( $a && $b && $a <=> $b ) ||
( $a && 1 ) || ( $b && -1 );
I changed the regular expressions to ensure that the entire name is captured (^ and $). I also changed them such that words that aren't suffixed by numbers still match (\d*). Finally, although, I'm not sure if this is important for your situation, I changed them such that any characters before the number suffix are allowed (.+?). The return is more complicated since it now handles the case where the $a
may not be defined since the word doesn't contain a numeric suffix.
Update: go with dragonchild's approach which is more concise and clear. However, do consider if any words may contain number other than as a suffix and decide how you want to handle this case (my code sorts these alphabetically).
