You will probably get different results depending on what your Custom
Permalink Structure is set to. If you're not using a numeric field at
the beginning of the Custom Permalink string, then Pages get handled
differently. For example, using %postname% alone would probably cause
the redirect to fail, because now the WP core code is checking for
complete URL paths for pages, to differentiate Pages from Posts. With
a numeric there, that code would not happen, and then the fall-through
to the 404 guesser might catch your page instead.

Test with the Month-Name structure and the Postname structure and see
if there is a difference.
