Sometimes you need an actual app. One that approximates your gestures, at least in spirit, is "Shake To Shuffle". It operates all the time, even when the screen has shut off. As long as music is playing, it works.
So perhaps someone has written an app to do your playlist gestures.

One minor problem is that the gestures don't appear to be sensed unless the screen is turned on. Is there any way to get around that?
I'm looking forward to digging further into Tasker!
