In the RWGPS Android app, I can sort my routes by name, but I can't see any way of sorting offline routes by name. I'm planning a four week tour, and as I don't know when I'll have WiFi available while touring, I plan to have all the daily routes downloaded to the phone before I leave. From the few that I've downloaded so far to have available offline, the order in which they appear seems pretty random.
Edit (7 May 2016): I see that a recent release of the RWGPS Android app has added this functionality. Thanks. Now, if only the app could remember that choice and make it the default, so that I don't have to choose sort by name every time every time I start the RWGPs app.
