Looks like Matti had the same question back in 2009:

http://old.nabble.com/sort-multidimensional-arrays-td26051359.html#a26059190

The proposed solution sounds similar to the response given to me, though 
my feeble brain isn't able to convert it into code. Interesting that the 
post mentions a variant can be used as well as an object.

Matti, if you're out there, do you have an example of how you sorted the 
example array in your post using these (or other) techniques?
