Marco, on this case it is better that you modify the /etc/init.d/zenloadbalancer script. If you try to run mysql with /usr/local/zenloadbalancer/zenlatency scripts, this don't work with iface task because on this point the ifaces are not configured.
You should search the startlocal and stoplocal section on /etc/init.d/zenloadbalancer and add on the end of this section your own command for run (startlocal) / stop (stoplocal) your own scripts. Remember delete your lines on /usr/local/zenloadbalancer/zenlancy scripts.
