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]}
}
If God had meant us to fly, he would *never* have give us the railroads.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
