Perhaps the count could be broadened?  That is, a count of RRSIGs for all
*non-apex* RRtypes other than DS, NSEC or NSEC3?  In a delegation-only
zone one would generally not expect to find much besides NS, DS and RRSIG
and NSEC(3) RRs, with the NS RRs and glue A RRs unsigned.

[ If the zone is signed via BIND, one might also find some signatures
  for TYPE65534. ]

For a somewhat more complete picture, below you'll find John Levine's data
augmented with recent delegation counts for all the CZDS zones including
the ones not listed him, where presumably the count of stray non-glue address
records was zero.

For example, for .biz, in addition to the two signed non-apex A records,
there are also three internal bookkeeping records:

  _nicname._tcp.biz. srv     0 0 43 whois.nic.biz.
  whois.biz.         cname   whois.nic.biz.
  www.whois.biz.     cname   whois.nic.biz.
