Drupal 6 - add javascript files for only specific node

The code below shows an example of how to add javascript files for a specific node (in this case nid of 339).

function discover_preprocess_page(&$variables) {

  if ($variables['node']->nid == "339") {
    drupal_add_js(drupal_get_path('theme', 'example'). 'sites/all/themes/discover/js/swfobject/swfobject.js', 'theme');
    drupal_add_js(drupal_get_path('theme', 'example'). 'sites/all/themes/discover/js/jquery/jquery-1.3.2.min.js', 'theme');
    drupal_add_js(drupal_get_path('theme', 'example'). 'sites/all/themes/discover/js/common.js', 'theme');

    // We need to rebuild the scripts variable with the new script included.
    $variables['scripts'] = drupal_get_js();

  }
}
