I like this code because it takes out the need for a module. The wider context for the code you have given me is:

my (@priority_numbers_in_order, @directories_to_transport) = Search_di
+rectories ($input_directory_C, $node);


my $count = 0;

for (@directories_to_transport){

  my $priority_number = $priority_numbers_in_order[$count];

  my $specific_recipient_directory = "$recipient_directory"."$priority
+_number";

  $dir = $_;

  opendir(DIR, "$dir") or die $!;

  my $file_name;

  while (<DIR>){
    $file_name = $_;
  }


  my $dir_and_filename = $dir.$file_name;

  rename "$dir_and_filename", "C:$specific_recipient_directory/$file_n
+ame" or warn $!;

  $count++;

}




sub Search_directories {

  my ($input_directory_CC, $node) = @_;

  my $directory_of_interest = "$input_directory_CC";

  opendir (DIRY, "$directory_of_interest") or die "Error opening direc
+tory : $!";

  my @directories;

  while ($_ = (readdir DIRY)) {

    print $_, "\n";

    if (-d "$input_directory_CC/$_") {
      print "This is a dir $_ \n";

      if ($_ =~ /\d$/){   
    print "This directory is a number: $_";
    push (@directories, $_);
      }
    }
  }
  close DIRY;

  print "\n\&&&&&&&&&&&&&&&&&&&&&&&&&&&&&\n".$input_directory_CC.@dire
+ctories."\n\n";



  for my $dir_num (@directories)
    {
      my @direcories_to_transport;

      print "\nforeach of the direcotories : $dir_num\n";
      my $input_dir = $input_directory_CC.$dir_num;
      print ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>$input_dir";
 
      opendir DIRY, $input_dir or die "Error opening directory $input_
+dir - $!";
 
      my @directories_time_tagged =
    grep /\d*$/,
      readdir DIRY;

      closedir DIRY;

      chomp(my @directories_time_tagged = <DATA>);
 
      for my $directory_name ( @directories_time_tagged ) {
    next unless $directory_name =~ /(\d\d\d\d_\d\d_\d\d_\d\d)/;  # Yea
+r_month_day_hour
    my $date_time = $1;
    my ($year, $month, $day, $hour) = split /_/, $date_time;
    
    my ($y_now, $m_now, $d_now, $h_now) = (localtime)[5,4,3,2];
    
    my $now = sprintf('%d_%02d_%02d_%02d', $y_now+1900, $m_now+1, $d_n
+ow, $h_now);
    
    if ($date_time le $now ) {  # If the date has been passed
      print "\nconditions have been met for $directory_name\n";

      my $directory_to_move = $input_directory_CC.$dir_num..$directory
+_name;
    
      push (@direcories_to_transport,  $directory_to_move);
      push (@priority_numbers_in_order, $dir_num);

    }
      }
    }
  return @priority_numbers_in_order, @direcories_to_transport;

I've not tested it though.
