I'm sure I composed a reply to this. Can't find it :-(

There are only 2 sorting fields, but you can fold an age-of-message 
component into your scoring, and then sort on that.

Scale your current scoring by 10 or maybe 100. The add a value in 0..9 
or 0..99 based on the message age. That needn't be a linear scale, you 
might use some fine grained low (or high?) values for recent messages 
and a coarser scale for older messages (ag a day, a week, a month etc).

There are relative time criteria in the PATTERNS section of the manual 
which you could use here for the scoring.
