IActiveScript::GetScriptDispatch should return a dispatch inerface that the
host can use to call into functions, methods, and variables of the engine.

This means an engine that parsed the following:
function test : string;
begin
result := 'succeeded';
end;
Should give a valid DispID when calling GetIDsOfNames on the dispatch
interface returned by IActiveScript::GetScriptDispatch, and execute this
function and return a Variant set to VT_BSTR,"succeeded" when calling
Invoke with that DispID.
