A note about eigrp tags. I've used them, and not had them show up on
downstream routers in the same domain.
I believe the reason was because changing a tag doesn't seem to cause a
route update.
My work around is clear the eigrp neighbors after a tag operation.
A#clear ip eigrp neighbors
And to see eigrp tags.
A#show ip eigrp top detail-links

The word 'understands' tags is a bit misleading. The routing protocols
do
not look at or use this tag they merely transfer the field from one to
another.
OSPF and EIGRP support 32-bit field but RIPv2 only has a 16-bit field.
Therefore remember to keep tags below 65535 if you are using RIP.

As per doyle's vol1 , only RIPv1 and IGRP do NOT understand tags .
so you can do this solution in the two directions like that
route-map ospf2eigrp deny 10
match tag 88
!
route-map ospf2eigrp permit 20
set tag 77
!
do the opposite for Eigrpp .
