You are missing an "org." in that dig command (and the +dnssec isn't
necessary), but yes, I see all the authoritative servers for org giving
a zero TTL for its DNSKEY RRset.

If one has the trust anchor for org configured in BIND, this has the
effect of zeroing the TTL for everything else from the org zone in the
local cache. What a good thing I didn't do this except on my workstation :-)

At the same time, the TTL for the SOA record for org is now 900 from 
the authoritative servers, see an earlier thread. Maybe we are seeing
some sort of transitional state?
