 Replying to [comment:73 ocean90]:
 > There is a problem with the {{{contextual_help}}} filter. It doesn't
 work for plugin pages/settings pages. This snippet doesn't return
 {{{$screen}}}, but it does in 3.2.

 Works for me.

 Note that the contextual_help filter will not always fire. It will fire if
 there is already old compatible help added to the page to form a "Screen
 Info" tab -- that help will then get filtered. It will also fire if there
 are no new-style tabs added, as it then serves as the basis for default
 help text.

 But if add_contextual_help() has not been called and add_help_tabs() has
 been, that filter can only fire if someone uses the contextual_help_list
 filter to add something specific to the current screen. You'll see that
 your code does not fire on post-new.php/post.php and index.php, as those
 have help tabs.
