wp_get_nav_menu_items order doesn't work

[markoheijnen]

Argument order doesn't work when output is ARRAY_A since on the end of function wp_get_nav_menu_items there is a usort on the $items array what will be returned.

Since out ARRAY_A is the default output this can give strange behaviour.

The code that gives the problem:

	if ( ARRAY_A == $args['output'] ) {
		$GLOBALS['_menu_item_sort_prop'] = $args['output_key'];
		usort($items, '_sort_nav_menu_items');
		$i = 1;
		foreach( $items as $k => $item ) {
			$items[$k]->$args['output_key'] = $i++;
		}
	}
