My question is the sort command appears to be failing when comparing 11-10-2004, 11-09-2004, 11-08-2004, 11-07-2004. The code should be removing the 11-07-2004 directory. The testing that was performed prior appeared to work fine when comparing directories that all had 11-0X-2004. Where did I go astray? 
sub dirname ()
{
    @date = ();
    $dirname = "";
    @date = localtime();
    $dirname = sprintf("%02d-%02d-%04d", $date[4]+1, $date[3], $date[5
+]+1900, @d
ate);
    @dir = ();
    opendir(DIR, "$path") or die "LOG->Can't open $path: $!\n";
    while (defined($file = readdir(DIR)))
    {
        if ($file =~ /^\.\.?$/)
        {
            next;
        }
        if ($file =~ /^\d{2}-\d{2}-\d{4}$/ && -d $file)
        {
            push(@dir, "$file");
        }
    }
    close(DIR);
    $records = 0;
    $records = $#dir + 1;
    if ($records >= 5)
    {
        print LOG "Program Error 8 - @dir\n";
        exit 1;
    }
    if ($records == 4)
    {
        foreach $item (sort { $b <=> $a } @dir)
        {
            rmtree("$path/$item") or die "LOG->Error is: $!\n";
            last;
        }
    }
    if (! -d "$path/$dirname")
    {
        mkdir("$path/$dirname", 0777) or die "LOG->Error is: $!\n";
    }
}
