Possible explanation for those timings:
a) The 50g had weak batteries such that half way it switched to the slow clock
b) The 50g was connected to the USB port. I'd have to look at the source code but I think I recall locking the clock at an intermediate speed when connected to the USB to keep the communications flowing. I might be wrong on this one, though.
c) The 50g had its large memory very dirty and had to run an exhausting garbage collection in the middle of that run. Try running MEM immediately before on both calcs to force a GC before doing benchmarks.

Other than that, it's impossible for the 39gs to be almost twice as fast when it's running the same code on the same hardware.
