I was able to get all classes to show by replacing function _pirets_explode_compact with the following, my changes are in the foreach loop...

function _pirets_class_explode_compact($data, $child = NULL) {
  $xml = new SimpleXMLElement($data);
  $return = array();
  $headers = array();
  if ($child !== NULL) {
    $xml = $xml->{$child};
  }
  if (isset($child->DELIMETER[0])) {
    $delim = chr(hexdec(strval($xml->DELIMITER[0]['value'])));
  }
  else {
    $delim = "\t";
  }
  // These substr() calls are trimming off the tabs at the beginning and end
  // of the rows without hacking off tabs representing blank columns as trim()
  // would.
  $headers = explode($delim, substr(strval($xml->COLUMNS[0]), 1, -1));
  foreach ($xml as $row) {
    $vals = explode($delim, substr($row->DATA, 1, -1));
    // Note that some idiot RETS providers may be serving fields with names
    // which are entirely numeric; for example, the list price will be in field
    // "173." Care must be taken that we don't prompt PHP to reindex arrays with
    // field data, because the indexes will change on fields with these numeric
    // field names, causing trouble down the line. For example, the line below
    // used to use array_merge() to combine the array with the crc32 value, but
    // this was prompting reindexing. Now we're using the + operator, which
    // achieves the desired result without reindexing.
    $return[] = array('crc32' => crc32($row->DATA)) + array_combine($headers, $vals);
  }
  return $return;
}

of course, I had to update function pirets_query_metadata_class to call my new function...
