Route redistribution

Here is the solution from IE workbook when redistributing between EIGRP
and OSPF.

I am confused with "match tag" I know you can tag the routes and stuff
but what is 890 or 390. Where these values came from? How can I look
these up?

Is this a correct solution ? can some one shine some light on that.

thnks

router eigrp 100
redistribute ospf 1 metric 10000 1000 1 255 1500 route-map OSPF->EIGRP
!
router ospf 1
redistribute eigrp 100 subnets tag 390
!
route-map OSPF->EIGRP deny 10
match tag 890
!
route-map OSPF->EIGRP permit 20
