I'm probably not completely clear on what you have to do, but this (not 100% perl) solution may give you a hint or two: 
use diagnostics;
use strict;
use Data::Dumper;

my %sprockets;
my %cogs;
open FILES, "c:/cygwin/bin/find.exe data  -type f -print|" or die "no 
+data";
while(<FILES>){
        m[sprocket_logs/(\w+)\.(\d+)]   and $sprockets{$1} = $2;
        m[cog_logs/(\w+)\.(\d+)]        and $cogs{$1} = $2;

}
print Dumper(%sprockets, %cogs);

The basic idea here is a two column table with the REs and tasks, separated by "and"s. You could (clearly) make it a 100% Pure Perl solution by writing your own find. It may not solve your problem directly, but it might give you at least a partial idea toward a solution.
