The best thing to do is make sure that the data come off the back end properly if possible. The JSON spec allows for numbers (unquoted), for example.
The next best thing may be to wrap the json you do receive in some encapsulating code. You could define some kind of clever sortBy method that introspects and decides if parseInt returns NaN or not. Or you could stick the parser right after the $http.get, so that your service munges the data to ensure all numbers are actually numbers. That last bit is something I used to do, as I had some extended data stored in an HSTORE column in my postgres database, which stores strings. So I define all my fields ahead of time on the angular side and type them, to coerce them properly when they come in. I've since switched to a JSON column type for that (extended stuff like experiments we may not keep or fields a small number of records have which don't need indexing), which does come off typed, so that's cool.
