Sort by a Boolean

How do I sort by a field that is a boolean? It doesn’t seem to be working. Here is my code.

Requests.find({
  requestDate: {$gt: new Date(minDate)}
},{
  sort: {scheduled: 1, requestDate: 1, submitted: 1}
});

Scheduled is a boolean field (either true or false).

Sorry I was resorting somewhere else. This code does work.
