I cannot reproduce. The following works fine:

--8<---------------cut here---------------start------------->8---
$ emacs -Q -l tramp --eval "(add-to-list 'file-name-handler-alist (cons 
(tramp-archive-autoload-file-name-regexp) 
#'tramp-archive-autoload-file-name-handler))" --eval '(file-directory-p 
"/home/albinus/tmp/out.tar.xz/")'
--8<---------------cut here---------------end--------------->8---

That makes a difference, indeed.
