This is strange. The "256" sounds reasonable (look at the top of 
:Mac:Lib:MACFS.py for the bits in the Flags field), but it should change 
if you set the lock bit (4096 should be added). You should however call 
GetFInfo() again, of course, the structure isn't updated live.

To make matters worse all this doesn't seem to work on OSX. I always get 
"0" back in the flags, and I can set whatever I want without effect. And 
I don't think this is a Python problem: xFiles (a utility to look at 
mode bits and finfo bits) also doesn't see changes made in the finder 
info window...
