I'm working on this ticket right now and looking at your route-maps it may
work but you have 1 extra statements in each for dealing with redistribution
between 3 routing protocols. The way I built mine for this ticket were
identical to Marko's in the video solution to the lab. The way I think of it
is:

1st statement - deny tags with the AD of the destination routing protocol
2nd statement - match and tag the protocol that isn't involved in that
particular route-map with its own AD
3rd statement - tag the source routing protocol with its own AD

route-map OSPF-2-RIP deny 10
 match tag 120
!
route-map OSPF-2-RIP permit 20
 match tag 90
 set tag 90

route-map OSPF-2-RIP permit 30
 set tag 110

route-map OSPF-2-EIGRP deny 10
