Once you've got your list of files, here's One Way To get the next filename to use: 
#!/usr/bin/perl -w
use strict;

my @files        = qw( 0000002.dat 0000102.dat 0000001.dat );
my $highest_file = '';
my $test_file    = '';
foreach $test_file( @files ){
 if( $test_file gt $highest_file ){
  $highest_file = $test_file;
 }
}
print "highest numbered file is $highest_file\n";

my $base_name = $highest_file;
$base_name    =~ /^(\d+)(.+)/;
$base_name    = $1;
my $suffix    = $2;
$base_name++;

print "Next file name is $base_name$suffix\n";
