node.js - Ordering results of eager-loaded models in Node Sequelize

I have a complex set of associated models. The models are associated using join tables, each with an attribute called 'order'. I need to be able to query the parent model 'Page' and include the associated models, and sort those associations by the field 'order'.

The following is having no effect on the results' sort order:

db.Page.findAll({
  include: [{
    model: db.Gallery,
    order: ['order', 'DESC'],
    include: [{
      model: db.Artwork,
      order: ['order', 'DESC']
    }]
  }],
})

I believe you can do:

db.Page.findAll({
  include: [{
    model: db.Gallery
    include: [{
      model: db.Artwork
    }]
  }],
  order: [
    [ db.Gallery, 'order', 'DESC' ],
    [ db.Gallery, db.ArtWork, 'order', 'DESC' ]
  ]
})
