I'm was trying use File::Finder to find a filename that is the X oldest file that matches a starting string. (I failed miserably...)
So I abandoned that and am trying anything that might work...
Here's an example:
from the directory listing;
test0
test1
test2
test3
test4
where the files were created in chronological order.

If I pass the parameters "te" and "2" it would return test1.

I'm running perl v5.6.0 built for aix.

This is the code I came up with so far. It will create a list based on the regex for the name and find the Xth file based on position in the list. I need that list to be in chronological order. 

#! /usr/bin/perl -w
$mask = $ARGV[0];
$position = $ARGV[1];

opendir(DIR,".");
my @files = grep { $_ ne '.' && $_ ne '..' }readdir DIR;
closedir(DIR);
foreach(@files)
  {
  if ($_ =~ m/^$mask/ig) {
    push(@result,$_)
    }
  }
print "Your file is: ".$result[$position-1]."\n";

Thanks to everyone for there input. I implemented Zaxo's
code and it does exactly what I need.

Thanks for the quick results.
