The challenge: with a POD no earlier then 1200 AD and no later than 700 BC, make it so that the population of Jews in 2010 will be at at least one hundred million.

That's kind of difficult, seeing as how 1200 AD is after 700 BC.
I assume you meant no earlier then 700 BC and no later then 1200 AD? In any case, having the Jewish Khazars survive and even thrive could work.
Or have medieval Christians have less of a "CONVERT OR DIE" mindset regarding the Jews. Maybe a writing by an early Christian author that is pro-Jewish?
