Well, that's what I get for not even checking the documentation before 
posting.  I forgot the first argument to 'modify_text' should be a state 
value.  The relevant states here are:

  - gtk.STATE_NORMAL for unselected text
  - gtk.STATE_SELECTED for selected text when the entry is focused
  - gtk.STATE_ACTIVE for selected text when a different widget is focused
