in reply to Golf: Arbitrary Alphabetical Sorting

I got a head start on this one, since I gave a recursive solution in the original thread. But I've never golfed before, so this is likely to go down in flames quickly... I believe it scores 110 as is (somewhat golfed, but probably not optimally).

sub o { $q=join'',@{$_[0]}; sort {$i=0; {index($q,substr($a,$i,1))<=>index($q,substr($b,$i,1))or($i++,redo)}}@ +{$_[1]} }

Update: Oof... difficulties is a nice way of putting it. A conditional statement fixes that, probably more cleanly than checking the string length repeatedly. Up to 125, I think--but then, I've already been clobbered.

sub o { $q=join'',@{$_[0]}; sort {$a cmp$b?do{$i=0;{index($q,substr($a,$i,1))<=>index($q,substr($b +,$i,1))or($i++,redo)}}:0 }@{$_[1]} }

    This is nice, but it has ahhh... difficulties with repeated words in the list to be sorted.
