I asked that very question in 737 school, and the answer I got was: don't use flaps above 20,000 ft because the limit airspeeds in the book are in indicated airspeed. If Boeing had published (and been paid for) flap limits in Mach #, it would be OK. But nobody wants that info because nobody can imagine why we would want to use flaps above 20,000 ft, anyway! Just what I heard.
