Here is a brief overview of the routing. AS 100 has 4 Routers, 1 PE, 2 ASBRs, one RR for VPNv4 (w/next hop unchanged). One of the ASBRs is RR for ipv4. AS 200 has 2 Routers, Both PE's and ASBRs.
The VPNv4 goes from one ASBR in AS200 to the RR in AS100 which is two routers away ( has the AS100 ASBR in the middle ) I redistribute the Loopacks of AS200 in to AS100's IGP for reachability. However, if I redistribute AS100's loopbacks in to the IGP of AS 200, it won't do any good because eBGP has a better Admin Dist that any IGP. Any concerns here? But recall that everything works individually, it is when combined I have issues. I can paste a show run of a ASBR if it helps. Let me know.

It would greatly help if you could post some configurations. The most important thing is - are you sure that you are tag-switching traffic between PE loopbacks and that next-hop information is not changed between two networks? Loopback interfaces are in IPv4 unicast table, as well?
