How to filter by duration in Youtube search API

Question

I am trying to filter the search results by duration (short) parameter. However, it still returns video up to 1 hour. In addition, the orderby parameter does not work. Here's the code (all other filters work):

var request = gapi.client.youtube.search.list({
  part: 'snippet',
  q: 'kittens',
  maxResults: 5,
  duration: 'short',
  orderby: 'published',
});

Is there anything related to the fact that these are “custom search parameters”? If so, how to use them?

Thanks in advance!

The search API reference says that you need to specify "type" as a video.

If you specify a value for this parameter, you must also set the type to parameter value for the video.

"type".
