Moving files based on file name

[Tor Rest]

This is the scenario:

I have the following ZIP files in a directory. The numbers represent
versions (the highest number is the latest version of the file).
mercury001.zip
mercury002.zip
mercury003.zip
venus122.zip
venus123.zip
venus124.zip
mars005.zip
mars006.zip
mars007.zip

I wanted to keep the latest version and move (copy and delete) the rest to
an archive directory. The directory should only contain the following
files:
mercury003.zip
venus124.zip
mars007.zip

I am a novice PERL developer. How do I accomplish this? Would appreciate
some examples. Thanks!

Here is one way to do it.
Tested only on Active State perl v5.8.0 on Windows XP.
Will not work if the file order from a glob is not alphabetic.

#!/perl/bin/perl

use strict;
use Carp;

# path to zip files
my $zipDir = "C:/tmp/zips";
die ("$!") unless -d $zipDir;
# path to archive
my $archDir = "C:/tmp/arch";
die ("$!") unless -d $archDir;
# get the directory listing
#default order is by file name on NTFS
#may not be the case on other platforms
my @zips = glob $zipDir.'/*';
die ("$!") unless @zips;
# reverse it
#puts latest file name for each type first
@zips = reverse @zips;
my %types;
for ( @zips )
{
my $fn = $_;
# strip everything up to the filename
$fn =~ s/.*\///;
# put the file type into $1
$fn =~ s/(.*?)\d//;
if( $types{$1} )
{
# for loop has already hit the latest of this type
#archive the rest
$fn = $_;
$fn =~ s/.*\///;
rename $zipDir.'/'.$fn, $archDir.'/'.$fn || die;
}
# for loop has not hit this type yet
# set the type key to 1
$types{$1} = 1;
}
