Maybe I'm missing something, but what would be the benefit to using this service to handle leaderboards for your iOS game instead of just baking in Game Center support and letting Apple take care of keeping your persistent score data?

Two benefits - multi-platform, and more extendable options.

I don't know how much you can extend this example (don't know much about Parse.com) but there's a whole lot of stuff that you can do with leaderboards that won't be handled out of the box by most platforms (except mine of course heh) - things like storing character and level information, screenshots, replays, etc with the scores, to make them a lot more interesting than a name and a number.
