Following up on a sharp observation of tye's in CB, I decided to check whether some of your sorts were in fact no-ops. Here's what I benchmarked, and the results:
srand 0;
my @fixture = map 'foo' . int( rand 1000 ). '.tla', 1..5000;
use Benchmark 'cmpthese';
cmpthese( -1,
{
naive => sub { ( naive( @fixture ) )[ 0 ] },
orcish => sub { ( orcish( @fixture ) )[ 0 ] },
schwartzian => sub { ( schwartzian( @fixture ) )[ 0 ] },
guttros => sub { ( guttros( @fixture ) )[ 0 ] },
}
);
__END__
Rate naive orcish schwartzian guttros
naive 3.05/s -- -65% -76% -87%
orcish 8.74/s 186% -- -31% -61%
schwartzian 12.7/s 317% 46% -- -44%
guttros 22.6/s 642% 159% 78% --
Note that the subs that are benchmarked return the first element of the sorted array.

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).
