This isn't working properly for me. If I give the sub 755, it produces -wxrw--wx. Very different from rwxr-xr-x.

So I revised the sub a bit: 

sub split_mode_to_string
{
   my @sections = reverse split '', $_[0];

   my @str_mode;

   for my $mode (@sections)
   {
       unshift @str_mode, $mode & 1 ? 'x':'-';
       unshift @str_mode, $mode & 2 ? 'w':'-';
       unshift @str_mode, $mode & 4 ? 'r':'-';
   }

   return join '', @str_mode;
}

Which gives the right permissions for 755. As well as all of the other tests I tried (001, 010, 100, et cetera). I think the issue with the original sub is that 755 shifted right by 3 is not 75 -- it's 94.
