See ldblib.c, in 3.2.

To create a list of strings:

 lua_Object result = lua_createtable(L);

To set the i-th entry in the list to string s:

   lua_pushobject(L,result);
   lua_pushnumber(L,i);
   lua_pushstring(L,s);
   lua_settable(L);

To return the list to Lua:  

   lua_pushobject(L,result);
   return;
