  Alternatively you could use 'cut' to slice out the desired field.
Something along the lines of 

  set string=`ruptime|tail +6|head -1|cut -d"," -f4`

 should work (head and tail to get only that line; cut to get the
fourth comma-separated field.)
 Maybe

  set string=`ruptime|sed -n6p|cut -d"," -f4`

  would work better, come to think of it.
