(Did you re-byte-compile files.el? Did you create a new Emacs?
Files.el is dumped into GNU Emacs.)
"Markers" inside the file take precedence over file name extensions.
Actually Emacs' description of what makes a PostScript file is
faulty. %! at the start of the first line is not enough (although it
mostly works). I corrected Emacs' setting with
(add-to-list 'magic-mode-alist '("%!PS-Adobe" . ps-mode))
which seems to work fine.

Yes. The reason is in TeXShop: it's author(s) make it an
imperialistic device similiar to Adobe Reader and its PDF plug-in:
the first line is allowed to only contain what TeXShop understands.
It won't keep pace with GNU Emacs that helpfully accepts a line like
%!TEX TS-program = latex -*- mode: LaTeX; coding: iso-8859-9; -*-

Forget TeXShop! Dump it on the dung-hill of computer history!
Of course you can complain on the Mac OS X TeX list, but Dick Koch
does not seem to like a helpful design in TeXShop.
And of course you can teach Emacs to understand the TeXShop syntax.
Particularly AUCTeX could be taught to use the TS-program for
compilation instead of
%%% TeX-command-default: "<some engine file>"
Would be interesting to now what other TeXing applications use to
remember the file's mode and TeXing command – to which extent their
imperialism has grown ...
There is no national science just as there is no national
multiplication table; what is national is no longer science.
