default sort of address db pop-up results

I'm very fond of using "^L" to do address completion, and the vast majority of 
results are coming from my exmh "Address Book" database. If the address isn't 
an exact match, I'd like to see the results in the database "pop-up" window 
sorted by date (ie., most recent first). I could see 
yet-another-preference-item, allowing users to specify the sort order 
(chronological or by closest match). For me, the most frequent use is that I'll 
want the address of someone with whom I've corresponded recently, even if it's 
not the best match.

So, any quick suggestions on how to sort the exmh Address Book database results 
by date?

Thanks,

Mark
