Correct:

Combination A
DSCP, Outer COS, UDP/TCP Source and Destination, IP SA/DA, outer Vlan
Combination B
IP SA/DA, Outer COS, Inner COS, DSCP, MPLS EXP, outer Vlan, Inner Vlan
Combination C
MAC SA/DA, Outer COS, Inner COS, DSCP, MPLS Exp, outer Vlan, Inner Vlan

I think the frustrating thing with the documentation is that when I look for things like restrictions and guidelines to configuring features, I look primarily in the section titled 'Restrictions and Guidelines'. I would think I'd have learned by now not to skim past more specific areas of documentation, but alas, my brain will not allow it.
