Congrats on the card!
They probably used a score from the TU04 formula. TU still provides the older TU98 score here and on their transunioncs (note the -cs) site.
Once more than half the nation's lenders shift to a new formula, myFICO changes as well, but it has to be done in concert with TransUnion.
I'm still trying to figure out how things are weighted differently in the two versions. I run across bits and pieces, but no big picture yet (for me, anyway.)
* Credit is a wonderful servant, but a terrible master. * Who's the boss --you or your credit?
FICO's: EQ 781 - TU 793 - EX 779 (from PSECU) - Done credit hunting; having fun with credit gardening. - EQ 590 on 5/14/2007
