define('META_TAG_TITLE', str_replace('"','',$review_on . $meta_products_name . $meta_products_price . PRIMARY_SECTION . TITLE . TAGLINE));

and replace it with

$meta_products_name .= " ID: " . $product_info_metatags->fields['products_id'];
define('META_TAG_TITLE', str_replace('"','',$review_on . $meta_products_name . $meta_products_price . PRIMARY_SECTION . TITLE . TAGLINE));

Insert right after (line 58)

if (isset($_GET['keyword']) && $_GET['keyword'] != HEADER_SEARCH_DEFAULT_TEXT  && $_GET['keyword'] != KEYWORD_FORMAT_STRING) {
    $keywords = $_GET['keyword'];
  }

this code

  if (strpos($keywords, ' ') === FALSE && is_numeric($keywords) &&  (int)$keywords == $keywords)
    {
      $exists = $db->Execute("SELECT products_id FROM products WHERE products_id = " . (int)$keywords . " AND products_status = 1");
      if( !$exists->EOF)
        {
          zen_redirect(zen_href_link('product_info' , 'products_id=' . (int)$keywords , 'NONSSL', false));
        }
    }
