The starter may have been good enough to start the car, but not to pass the test... Quite possible with 12 year old parts....
If you find the alt is bad, make sure you have the battery tested after it is replaced. as Gav-O pointed out, dying alternators can be hell on batteries, even new ones.
By the way, what engine do you have in your focus?
I don't know about the zetec, but on the SPI the alt. is a real easy swap. hardest part is getting the accessory belt on at the end. Might be a good idea to check your belt tensioner while you have the belt off.
