I can confirm this for 

Org-mode version 7.4 (release_7.4.215.g1350)

GNU Emacs 23.2.1 (i486-pc-linux-gnu, GTK+ Version 2.20.0)
 of 2010-12-11 on raven, modified by Debian

Setting (setq org-todo-keyword-faces '(("WAIT" . "lightgoldenrod2")))
seems right according to the docstring:

,----
| This is a list of cons cells, with TODO keywords in the car
| and faces in the cdr.  The face can be a symbol, a color
| as a string (in which case the rest is inherited from the `org-todo' face),
| or a property list of attributes, like
|    (:foreground "blue" :weight bold :underline t).
| If it is a color string, the variable `org-faces-easy-properties'
| determines if it is a foreground or a background color.
