I make your original 79 chars.
sub a {
return$i if$_[0]==495;$a=join'',sort{$a<=>$b}split//,pop;$i++;a((rever
+se$a)-$a)
#23456789_123456789_123456789_123456789_123456789_123456789_123456789_
+123456789
}
if you are sorting single digits then perl's default alphanumeric sort will give the same result as explicitly defining a numeric sort. #71
update: just realised you can use $_ instead of $a. #69

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).
