Restarting NTP

I'd like to set up a rule that would restart NTP when two conditions
hold:
  a) The host is connected to my ISP (no point to bothering if I can't
     get out to an external time source), and
  b) The set of NTP servers the host is _trying_ to sync against _does
     not_ include some of the external ones.

I could evaluate the first via something like:
   PPPCOUNT=`route -n | grep ppp | wc -l`
The latter something like:
   NTPSERVERS=`echo dmpeers | ntpdc | wc -l`
... And I'd want to do something like:

shellcommands:
  ntpserver::
    "if $PPPCOUNT > 0 and $NTPSERVERS < 5; then
      /etc/init.d/ntp restart
     fi"

I could write an external script that evaluates this; that may well be
the answer I go with.  Is there some way I'd best evaluate this inside
cfengine?
