It depends on the gears at which you terminate these two links
and create port-channels. If you equipment can do load-balance
based on MLPS labels - good. If not, MPLS traffic possibly will
be bound to only one wire. Also it depends on what exactly your
mpls traffic will be in this point of the network - mpls labels
can be removed completely if you not use explicit null labeling.
