Ah, I see mj updated the score table already. That was quick. Hope you don't mind updating it again

5,430,940 - DocHauser - Bolt/Nail - Stage 4 - MAME (JP)
I had been playing the US version since I assumed the default settings were easier. Don't see a huge jump in difficulty in the Japanese version, but maybe there's a slight increase in the number of bullets, which increases the scoring potential.
Anyone gotten the hang of the Stage 4 extend? It's a bit tricky.
