--------------------------+-------------------------------------------------
 The following lines in wp-includes/user.php evaluate $meta_value passed to
 update_usermeta() (current line #s from trunk):

 {{{
 397         if (empty($meta_value)) {
 398             return delete_usermeta($user_id, $meta_key);
 399         }
 }}}

 A numerical or string zero evals as empty, resulting in the inability to
 store zero as a meta_value.

 A better test for truly empty might be:

 {{{
 397         if ($meta_value == '')) {
 398             return delete_usermeta($user_id, $meta_key);
 399         }
 }}}
