Dan,
I believe this question assumes that Router A is receiving the route via
another connection under normal circumstances. If this route dissapears,
then it should accept a default from router B.
You can use the local preference attribute to make the route coming from
router b less preferred under normal conditions but it will use it if it
does nto have a mor preferred route. Halabi has lots of examples of this
type in his book.
