It also hosts example.org and sadly I can't change that.

I just tried that and it works, at least almost:
dynamichost1.example.org has address ip.ad.dr.ess
Host fra.example.org not found: 2(SERVFAIL)
Host fra.example.org not found: 2(SERVFAIL)

Why do I get one correct response and two servfails?
Couldn't find an error in the logfiles.
