Have you considered using Python? It depends on your target platform, but Python is an open source scripting language that is easily interfaced with C and C++. It is an extremely powerful language way beyond UnrealScript but obviously with the overhead that comes with such an expressive power.

Implementing A Scripting Engine by Jan Niestadt

Can anyone point me in the direction of some information on the subject of using scripting in a game engine (source code, concepts, how to start implementing)? I've done some work writing a compiler that compiles C-style code into a severely limited form of objects, states, and scripts. Of course, I'm trying to write something bigger and better. You'll probably laugh if I said I wanted to create something like UnrealScript (only on a much much much much much smaller scale), but now you have the idea of the kind of info I'm looking for. Thanks.
