I'm afraid not. It currently orders them alphabetically by the name. A quick
hack when I needed our test server datasets ordered. Adding a sorting capability
is on my list of tasks for the catalog generator.

Yes.

Creating DODS AggServer config files is also on my list for the catalog
generator.

I'm planning on focusing on the catalog generator for a few weeks starting
towards the end of May. A refactoring of the code; some rethinking of how the
datasetSource, datasetFilter, and datasetNamer elements are handled and how they
interact (sort and aggServer probably fall in here); and adding other metadata
capabilities. So, keep the ideas coming.
