Ever since the hotfix that tried to "fix" some weird sort of exploit with the "grindy" trick, the score multiplier simply broke. I seriously hate grinding on a single rail for forty minutes on The Pearl like a lot of people do, but this "fix" simply made impossible to earn standing in a non-exploitative way. I used to run around the Vallis chaining lots of tricks and grinds, earning a x30 multiplier with a decent amount of tricks. Now, ever since then, the score multiplier simply doesn't apply!
