It could be a nice user interface improvement to provide a popup window containing the subqueue manipulation form. I imagine a "Reorder" link in $links. If the node is only in one subqueue, then display the subqueue ordering interface in a popup. If it's in multiple subqueues, in the popup first display a link for each subqueue, then display the ordering form based on the user's choice.

This prevents the user from having to manually click through several pages, change the node's position in a subueue, then navigate back to the node. Another way of making this page flow easier would be to add ?destination links back to the current page for subqueue manipulation links.
