within the TeeAction?

Yes, "Subsequent rules are processed after this action"

a dedicated pool to which notifications are sent (based on checking the 
OpCode). To do this, you would most likely have to write a few lines of 
Lua code. Would this be an alternative solution? What do you think?

I don't know, sorry. I'm also not sure I understood the question 
correctly. Apart from TeeAction, a query can only be forwarded to one 
server of a pool. This is possible out-of-the-box with a Rule and a 
PoolAction. What would be the purpose of the mentioned Lua script? Do 
you mean send multiple Notifies from a LuaAction? Then I don't know.
