I don't recall how the CMTSs are set up, but it might be that each Static IP block will only work on the CMTS that the business account's node is on.
Seeing as Cablevision owns and issues IP addresses from non-portable blocks to their customers, that would be an educated assumption.
I know the addresses from DHCP work like that, but the static IP ranges don't come from the DHCP servers, which is why I'm not 100% certain.
