This is seriously confusing. I'm guessing the second block of text is
the zone file, grep'd for "sci" too?

Anyway, multiple CNAMEs for the same record aren't valid. A record have
two /canonical/ names is a contradiction in terms.
[ There is a multiple-cnames option you can specify in your named.conf,
  but don't use it ]

Do it anyway, right now. There are known, serious security problems with
8.1.2. See http://www.isc.org/products/BIND/bind-security-19991108.html
