Have you verified that you're advertising the routes
to them?  In Cisco-speak, does

sh ip bgp nei x.x.x.x adv

return what you're expecting?

Also, assuming that your backup ISP is either directly
connected to (or one transit hop away from) your
primary ISP, 3 prepends is too many for what you want.
 Try 1 prepend first.
