OK for this particular constraint.

Did you think about Lisp-ish languages, most probably Scheme, to
fulfill this task ? Weak typing, extremely simple syntax and a very
small memory footprint makes it a scripting language of choice.

There are many free Scheme implementation written in C, many of them
being specifically targetted at being extension/scripting
language. The GNU Guile project may in the spirit of what you're
looking for (see http://www.gnu.org/software/guile/)

Funny enough, some small (and canonical) Scheme implementations fit in
2000 lines of C code. You might even want to write it yourself :)
