Class Based TE is for transport of IPv4 traffic I guess, your MPLS L2 VPN frames get an MPLS EXP field but you may need to mark in some way to use a specific class of tunnels, otherwise the risk is to try to use a "default" tunnel and it has to be seen if this kind of traffic has enough resources to be successfully setup.
Another point to check is MTU if there is an additional overhead for Class Based traffic engineering but this should lead to problems to carry big user packets but PPPoE negotiation should be successful
