I don't think Rumple knew about Zelena cause Cora had her before she met Rumple. I believe he first discovered Zelena when they met when Zelena entered the palace after discovering she had a sister. I think before that he considered Regina first-born and the one to do his deed but when he met Zelena, perhaps he discovered since she is first-born she could do the task but then he realizes Zelena isn't the right one and decided maybe the second born is the one to do it.
