If you're switching views via the Project and Context buttons in default toolbar, what you're really doing is switching between two Perspectives that assert specific view settings on the window. The Project perspective includes the sorting behavior you're seeing there; pressing that button changes the sort, in other words.

You'll either want to edit those Perspectives to sort the way you'd prefer, or create a new Perspective that includes your preferred sort and add that to the toolbar. (The Help menu material has info on how to do all of the above.) Hope that helps!
