Having set a pre-planned trap really is the only possible way for Lord Tywin to be directly involved. I think I've allowed by myself to be misled because Robb had other enemies who want him dead, beginning with the Karstarks. And, then of course, there is the lack of sufficient time issues associated with bringing Lord Tywin into the loop.

I'd also thought that Lord Bolton telling Rob "Lannisters send their regards" was a bit of script misdirection to fool the viewer. I'd thought Lord Bolton was simply repeating Jaime Lannister's message, "The Lannisters send their regards." There have been a few murders and attempted murders during the series, and in every case there was an attempt to make it look like someone else was responsible. Lord Tywin cleared the air on that count in the season finale. It surprised me. Thanks for responding so quickly.
