What do you mean by default behavior?  The default getProperty and 
setProperty implementations are stubs that return true.  Can't you just do

    if (!JSVAL_IS_INT(prop))
        return JS_TRUE;
    return ins->setBuiltinProperty(JSVAL_TO_INT(prop), value);

here?  (I'm pretending setBuiltinProperty returns a boolean indicating 
error/exception with false.)
