As I know nothing about Javascript, I'm probably not going 
to be as much help as Stephen's replies.  Ignore what I say 
if it's no help to you.  :-)

For what it's worth, you can sort arbitrary objects that are 
in an array in C/C++ (i.e., array of objects).  In C, you 
give it a sort function that tells it what the object looks 
like.  i.e.,

http://www.cplusplus.com/reference/clibrary/cstdlib/qsort/

Of course, these objects need to be placed in an array in 
some initial linear order.  If it was in some kind of 
associative array, then you would need to pull them out and 
throw them in an array for qsort () to work.

Perhaps languages like Perl and Python can do something like 
this -- I've never tried.  Examples of sorting objects in 
C/C++ are somewhat rare; most examples stick with easy cases...
