Without having done any testing, testing, this would seem to do what
you want.  Basically, it's just a property-assign with a units
conversion.  There is a fancier property used by the VSI which
computes vertical speed from the static pressure, too.

<binding>
 <command>nasal</command>
 <script>
  setprop("/autopilot/settings/vertical-speed-fpm",
          60 * getprop("/velocities/vertical-speed-fps"))
 </script>
</binding>
