Super Mario Bros. Deluxe - 3-1 Maximum Score WITH L+R (TAS)
L&R is a lot harder to optimize, but I think this might be the highest possible score. I have 11 usable frames on the timer at the end, but I don't think there's much I can do with them. The 10,000 hit wasn't possible last time because there either wouldn't be enough time to make up for it, or enough time to hit the other Koopa coming down the stairs.
If you want to see this with the LUA script I used, here are the files you'll need:
