 The following suggested patch adds a new `wp_get_object_terms_args` filter
 in `wp_get_object_terms()` function in order to filter the arguments in
 retrieving the terms associated to the post. For example:

 {{{#!php
 add_filter( 'wp_get_object_terms_args', 'wp_get_object_terms_args_hook',
 10, 3 );
 function wp_get_object_terms_args_hook ( $args, $object_ids, $taxonomies )
 {
         $args['orderby'] = 'term_order';
         return $args;
 }
 }}}

 `wp_get_object_terms()` is widely used to retrieve terms taxonomies but
 it's not possibile to set the `term_order` as orderby clause everywhere in
 a simple manner:

 - The posts list
 Even if in the post list (''wp-includes/category-template.php'') you can
 uses `get_the_terms` filter to get ordered terms, you have to write
 additional code

 - The metabox taxonomy (advanced edit)
 It seems that there is no filter/hook that allow to set the `term_order`
 as orderby for terms to edit (the `terms_to_edit` filter in ''wp-
 admin/includes/taxonomy.php'' seems to come too late :-( )

 - The XML-RCP interface
 The patch filter will be used in `wp_getPost()` XML-RPC interface method
 by returning ordered terms


 Comments and suggestion are appreciated

 Kindest regards

 PS1: Alternatively, with the `get_object_terms` filter you can do the
 orderby (among all other arguments) at the price to  loose all the logic
 inside `wp_get_object_terms()` so you have to rebuild the terms array from
 scratch.

 PS2: The attached patch can be applied to 4.4.2 version too.
