Others have already covered off on the topic of moving the redundancy issue out of your network and back into the carrier's

Last time I ran this up in the lab (admittedly some time ago) you couldn't do this well with LDP-VPLS - both links back to the PE will run active-active and you'd need to run spanning-tree to block the loop and act as your fail-over mechanism.  If your carrier is using BGP-VPLS, then it is possible to identify both of the services at an end as belonging to the same site and use this as part of a tie-breaker as to which is service should currently be active.
