[Plugin: Post Types Order] Plugin clashes with orderby parameter in query_posts

With this plugin activated, the orderby parameter is ignored in a custom query:

e.g.

$args = array (
	'post_type' => 'mytype',
	'orderby' => 'rand',
	'posts_per_page' => -1);

$psites = new WP_Query( $args );

The rand parameter is ignored when the plugin is active.

Is there any workaround – we want some of our pages displaying the posts in the order determined by the plugin, but we also need to be able override that in custom loops
