I stumbled across this thread while searching for tips to make my Mun mission lighter… Instead I may have the record for a rocket launch! It's a pretty basic Apollo-esque mission architecture, and it could definitely be optimized a bit. I was carrying >200 m/s extra dV at Kerbin interface, and I used essentially none of the 3.0 units of monoprop I brought for docking. A more skilled pilot could probably pare down the fuel, or try for the landing targets, or both. 23.720 t -> 2372 base points -150 for stock parts -100 for no autopilot -40 for docking with RCS = 2082 total points, if I'm reading the rules correctly. Edit: I reduced the monoprop to 1.0 and took 100 units of fuel out of the third stage. That brings the mass to 23.149 t, but with only 3% spare delta-v I haven't been able to successfully fly the mission yet. An autopilot mod could presumably do it, and also land at the monument, for a score of 2075.
