I have a pair of mpls routers running BGP and redistributing routes into EIGRP.
The redistribution is controlled via a route-map
The route-map has a match statement based on bgp community tags
router eigrp 1
default-metric 100000 100 255 1 1500
network 10.3.128.53 0.0.0.0
network 10.80.95.148 0.0.0.0
network 10.80.95.156 0.0.0.0
network 213.12.66.178 0.0.0.0
redistribute bgp 65139 route-map bgp->eigrp
route-map bgp->eigrp permit 5
match ip address prefix-list eem-leak-2
set metric 100
set tag 4445
!
route-map bgp->eigrp deny 10
match community cw-mgt-routes
!
route-map bgp->eigrp deny 20
match community local-eigrp-routes
!
route-map bgp->eigrp permit 30
match community cw-voice-subnets XXXXXX-voice-subnets
set metric 100000 50 255 1 1500
set tag 4445
!
route-map bgp->eigrp permit 40
set tag 4445
Named Community standard list cw-voice-subnets
permit 1:10
permit 1:20
Named Community expanded list XXXXXX-voice-subnets
permit _65139:1([0-9][1-9])_
My question is if the prefix being redistributed has a tag of 7100
sh ip bgp 10.232.250.0/24
BGP routing table entry for 10.232.250.0/24, version 8198

Should this not be redistributed with the default metric defined under the EIGRP process or should the permit 40 entry of the route-map have the default metric defined.

You are correct: if it is an eBGP route that is being redistributed, it should get the default metric
If you are redistributing iBGP routes, configure 'bgp redistribute-internal' under the BGP process...

Should this not be redistributed with the default metric defined under the EIGRP process or should the permit 40 entry of the route-map have the default metric defined.
It will take the default metric values applied in the eigrp process, Unless as you have queried, You set different values with either the redistribute command or in the route-map stanza, both of which which will override the default metric values stated in the eigrp process.
