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__
