2008052803 is a ten digit number.

Your pattern matches eight digits with a \b word boundary at each end
so it will never match a ten digit number. Also the character class
[1-31] could be more simply written as [1-3] (repeated characters are
ignored.)
@array = qx#ls -tr $directory/$ARGV[0]*#;
Why not do that directly in perl:
@array = map $_->[0], sort { $a->[1] <=> $b->[1] } map [ $_, -M
], glob "$directory/$ARGV[0]*";
#2008052803

hey thanks!
this works fine now
} elsif ( $ARGV[0] =~
m/\b2008(0[1-9]|1[12])(0[1-9]|1[0-9]|2[0-9]|3[01])([01][0-9]|2[0-3])\b/ ) {
@array = qx#ls -tr $directory/$ARGV[0]*#;
#2008052803
} else {
I will try that direct perl solution as well!!
