We need to talk about this one. Adding sort options means adding indexes to the database (which means we should think about how exactly we will combine them first). We also need to think about performance, issuing one search query for half the scans will be very difficult to handle server side, and will definitely kill the server when we have spikes from TV. The best solution would certainly be to do it on the mobile device with the offline database. It would also make a much better feature (works offline, more personalisation without loss of privacy).
