I agree with your suggestion to use a ST but my preference would be to use a regex to pull out the month, day and year elements and do a three-way sort, greping only those filenames that match.
use strict;
use warnings;
my %months;
@months{qw{
jan feb mar apr may jun jul aug sep oct nov dec}} =
0 .. 11;
my $rxWanted;
{
local $" = q{|};
$rxWanted = qr
{(?x)
\A
webadmin
_(@{ [ keys %months ] })
_(\d\d?)
_(\d{4})
\.log
\z
};
}
print
map { qq{$_->[0]\n} }
sort {
$a->[3] <=> $b->[3]
||
$months{$a->[1]} <=> $months{$b->[1]}
||
$a->[2] <=> $b->[2]
}
grep { defined $_->[1] }
map { chomp; [ $_, m{$rxWanted} ] }
<DATA>;
__END__
.

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).

or How to display code and escape characters
are good places to start.
