I once had a GUI that displayed the contents of a dict as a tree. The user could add entries, and the entries would display at the end. Hence, the ordered dict. I could have kept the order separately, but what was the point? I just whipped up a homemade ordered dict class, it worked fine, and I didn't have to worry about keeping them synchronized.
