in reply to $a <=> $b

roboticus answered the immediate question, but note that this is why you should avoid using $a and $b a general purpose variables: they are magical and should really only be used inside sort.

Note too that using sort without a {...} bit is like sort {$a cmp $b}. That is, sort's default is to do a string sort.

True laziness is hard work
