Does unrealscript allow the address-of operator (&)?
If so, just make a global variable of a structure containing game data and write the address once to a file for reading by the c++ driver.

Once you have the address you should be able to use ReadProcessMemory and WriteProcessMemory on a similar structure ( with all offsets correct ) written in C or C++.

I have not done that much reading on unrealscript so I don't know if their virtual machine uses the actual addresses of objects or if it has it's own memory system.

I guess I'll install UT and check out some more options.
