Coming from FAA land, my understanding is that a frozen ATPL is just a CPL with ATPL subjects passed. A F-atpl is flight school marketing talk for CPL + IR + ATPL theory subjects passed. You only have a CPL.
Best to list it as a CPL; as that is exactly what it is in all countries that do not have the eurocentric fATPL. Try converting your JAA f-ATPL to a TC, FAA or CASA f-ATPL (insert most other national aviation authorities) and see how that goes.
All I'm saying, is that it just may rub an operator the wrong way, and if he is one of many candidates applying, why do that.
