You see, apparently, both Ozluminati and the Coven had no idea where Spring was, which means that she was not a threat to Salem at the moment and they could probably take care of her later.

Ruby, however, was a Silver Eyed warrior that managed to seriously injure one of their own, even though they apparently have experience dealing with them. If left unchecked, Ruby could become a powerful weapon for Ozluminati, which is why Salem sent after her. As for what she intended to do with Ruby, your guess is as good as mine.
