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__ . .. webadmin_jul_10_2007.log webadmin_jul_11_2007.log webadmin_jul_12_2007.log webadmin_jul_13_2007.log webadmin_jul_14_2007.log webadmin_jul_7_2007.log webadmin_jul_8_2007.log webadmin_jul_9_2007.log user.log

The output is as yours.

Cheers,
