Your logic above is broken; if any attempt succeeds, you undo it by trying another method. If you don't care about trying a lot of possibly broken path alternatives, you could do this:
open(MENU, $bestpath ) or
open(MENU, $nextbest ) or
open(MENU, $worseway ) or
open(MENU, $fallback ) or die "No way to reach it!";
do_stuff_with MENU;
close(MENU) or die "Scary failure trying to close it!";
If you're just asking what the right syntax would be for a UNC path, it's
\\netbioshost\sharename\path\to\file.ext.
