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.)

Why not do that directly in perl:

      @array = map $_->[0], sort { $a->[1] <=> $b->[1] } map [ $_, -M ], 
glob "$directory/$ARGV[0]*";
