Thanks for pointing out, that should be fixed in r12206.

I think it's sufficient to use only degrees within user interface as
it's most common unit (ok, some might want use grads). But for
data-driven rotation of labels it could be considered to give the user
chance to set both units type and rotation style.

The conflict resolution is done for all layers at once. In the
labeling settings dialog you can also set priority for each layer.
