Hey doug: I think i was mistaken the last time we talked.
As you've discovered (and as Koji verified) Sort by function is not
available in Solr 1.4.
What you can do however (w/o applying any patches) is query on a function
so that the function result is used as the score, and then use filter
queries to constrain the resulting documents. for simple "i need to sort
by a function" purposes this works fine, what it can't deal with (cleanly)
is "i want to sort by a field desc, and then i want a secondary sort on a
funcA() asc, and then a tertiary sort on funcB() desc, ..."
ie...
q={!func}sum(sum(f1,f2,f3),sum(pow(x,4),f1))&fq=your+query&sort=score+desc
