You can save a single character by using a glob, such as:
sub o { ($l,*w,$")=@_;sub g{$_=pop;s/./chr index"@$l",$&/ges;$_}sort{g($a)cmp +g+$b}@w }
So *w ... @w instead of $w ... @$w.

'1e9' or 'chr' vary only in that '1e9' would support an alphabet of length > 255, but if you're using UNICODE, then chr would likely return two characters anyway.
