The easiest way to do that (in Ruby--Perl syntax is basically the
same, Javascript syntax shouldn't be too different) is simply:

my_object.keys.sort{|a,b| a[:some_key] <=> b[:some_key]}.map {...}

Ruby has a hash that keeps the keys FIFO ordered, if that makes sense.
The first key you put in is the first key that
GoogleOnlyKnowsTheNameOfTheHashClass#keys will return.
