The minimal example works fine:

emacs-24.4 -Q -l foo.el foo.txt

where foo.el has contents:

  (define-minor-mode foobar-mode "blah" :initial-value nil
    (font-lock-add-keywords nil '(("foobar" . 'font-lock-warning-face))))

  (add-hook 'text-mode-hook 'foobar-mode)

and foo.txt contains:

  foobar

foobar gets font-lock-warning-face.

So your problem may be specific to your specific modes.
