How can I use a standard work item query to show in Urban Turtle's Priority Order?

Edit Subject

Urban turtle appears to be using some special logic for the Stack rank in order to determine the priority that things are displayed in on it's tabs. Not just in ascending or descending order.
As a Product Owner I would like to be able to create work item queries (such as All Open User Stories Not In A Sprint) and order them by the priority as seen in the urban turtle tabs so I can focus on the most important user stories when doing project planning.
