BeenthereIL,
I would hope that the scout/recruiter would take a little more into consideration than just velocity and height. I think what you are saying is that there is more upside potential with the taller player. However that could be turned around and it could be said that if a taller player has more potential to throw hard, then a shorter player throwing the same velocity must have better mechanics and thus control over his pitches. Do you want to take the risk that you can straighten out the taller players mechanics, which have been ingrained in them over many years. I say go with the better pitcher regardless of height.
