If you are using checkboxes for your survey, you can set values for the individual items in a checkbox


Adding a hidden field as a total and using Javascript to keep the hidden field up to date will allow you to sum totals of a form's quiz


<script type='text/javascript'>
  var update_total = function(){
    var total = 0;
    $('%FORM.HTML_ID% .checkbox input[type=checkbox]:checked').each(function(){
      total += parseInt($(this).val());
    });
    $('%FORM.HTML_ID% input[type=hidden].activedemand-input').val(total);
  };
  $('%FORM.HTML_ID% .checkbox').each(function(){
    $(this).parent().children(".activedemand-label").css("display", "table-row");
    $(this).css("display", "table-cell");
    $(this).parent().css("display", "table");
    $(this).on("click", update_total);
  });
  update_total();
</script>



Consider posting the hidden field to a custom field on the contact
