Comment (by tyxla):

 @valendesigns these are disallowed by design, as they are used internally
 by WordPress. You can read more about these three here:
 register_post_type#Reserved_Post_Types] - quoting:

 In addition, the following post types should not be used as they interfere
 with other WordPress functions.


 In a nutshell, using any of these as the post type's name would conflict
 with the built-in WordPress parameters. The `action` is internally used to
 send a specific action (often in the administration, or in an AJAX call),
 the `order` is a built-in query var for specifying ASC or DESC for a
 query, and the `theme` is internally used by theme installer, editor and
 upgrader in the administration.
