A wagging tail is a voluntary action (happy dog wags its tail, unhappy dog has stiff tail, scared dog as a lowered tail). For dogs, the tail is an actually something that will indicate mood.

The wobble/head tilt/corkscrew/whatever isn't seen (as far as I know) as something that the animal does because it wants to and has little to no bearing on the "mood" of the snake, just that it seems to happen more frequently when the animal is put into a high stress environment (shipping, feeding, etc).

I would believe this is why it is seen as a defect in an animal.
