Now that I think about the problem more, I really want
to sort an array of dictionaries according one of the
keys of each.  Could I use:

array.sort(key = something)

Where something looks at the proper item in the
current row?  I can't quite visualize how to pull
the item out of the dictionary.

Thanks
