Just keep in mind that what we see as tilt on that shot could also be a lower frequency additional AC or variation of a base DC signal being modulated by the waves we see.
If we have a video of the scope this would be apparent. If it was tilt that same video would show it as the pic shows it.
In addition.... any nearby strong magnetic dipole could cause tilt. This would not be limited to the Magnacoaster setup he may have had nearby. It can also be caused by an apparent magnetic vortex ( or electrostatic ) with the right strength and proximity.
So, I don't think we nailed a scope problem for him. The tilt can still be another puzzle piece.
It could be many things, but the most obvious and most likely explanation, is that the scope trace rotation is in need of adjustment. Just to put the lower frequency modulation question into perspective, assuming the RPM=1500, that amounts to 25 rots per second, and since there are 8 or 9 magnets per rotation, that puts us on the order of 800Hz try 225Hz. So, are you seriously thinking that there could be some few Hz signal modulating that wave form? .99 EDIT: corrected frequency
