Just for the sake of TIMTOWTDI:
$max = ($x,$y)[$x<$y];
$min = ($x,$y)[$x>$y];
which is a golfed version of your 2nd variant: (sort-of) a one-step sort which eliminates building a code block frame and the call of sort. Ternary is cheaper, since it doesn't involve bulding a list.
update:
I've been working at a place where restrictive coding standards prohibited ternary and forced me to write
if ($x < $y ) {
$max = $y;
}
else {
$max = $x;
}
- which is as cheap as ternary (I guess) but looks convoluted to me - among other hilarities. Good riddance.

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).
