The answer I gave to the same question last Thursday is :

You can only update one DNS server from DHCP. The way most people 
deal with multiple DNS servers is to run one as a master for the 
zone, and one or more as slaves - using the normal zone transfer 
mechanisms.

It would be quite a difficult, and impractical, task for the DHCP 
server to manage two separate updates - either of which could fail 
and need re-trying. You could very easily end up with inconsistent 
DNS servers.
