Try out this

maybe bit trip

Beat Hazard

AaaaaAAaaaAAAaaAAAAaAAAAA!!! for the Awesome

was looking around the store page and didn't really know how to tell if it runs on linux or not but. Sonic the Hedgehog games run with a score system at the end.

Edit: also FTL: Faster than Light

this game looks like designed for a sort of competition.

Shatter
Super Hexagon
Savant - Ascent
Receiver (doesn't really have a complex score, just how far you got from 0-11, but it's such a great game)
The Puppygames games: Revenge of the Titans, Ultratron, Titan Attacks!, Droid Assault
And to second other people: Beat Hazard, AaaaaAAaaaAAAaaAAAAaAAAAA!!! for the Awesome, FTL (several hours), Race The Sun

Stuck on Q1. Dont know what you are looking for.
Free bump

World of Goo - Tower of Goo.

I can't find the puzzle?

Savant - Ascent.

Definitely anything from the BIT.TRIP Series.

Also Joe Danger 2: The Movie and Trials.

I can't say for sure these all have Linux support, but definitely worth a look.
