Backbone Menu Not Sorting

I'm having trouble getting a Backbone collection to sort properly. I inherited the project, so there may be some shenanigans someplace else, but I want to rule out any syntax error on my part.

The project uses a JSON file to handle the data:

"classifications": [
            {
                "name": "1 Bedroom",
                "alias": "1BR",
                "id": "1BR",
                "menu_desc": "Residences"
            },
            {
                "name": "2 Bedroom",
                "alias": "2BR",
                "id": "2BR",
                "menu_desc": "Residences"
            },
            {
                "name": "3 Bedroom",
                "alias": "3BR",
                "id": "3BR",
                "menu_desc": "Residences"
            },
            {
                "name": "4 Bedroom",
                "alias": "4BR",
                "id": "4BR",
                "menu_desc": "Residences"
            },
            {
                "name": "Common Areas",
                "alias": "Common",
                "id": "Common",
                "menu_desc": "Resident Amenities"
            }
        ]

Previously, there were no one-bedroom units, and the order in which it rendered was this:

I added the one-bedroom classification, and suddenly the order was this:

I did some digging and found documentation about the comparator property, but it only seems to apply to collections. This project doesn't use a collection for the classifications. It does for the submenu items (which floor the units are on, etc.), but not the main menu:

    var MenuClassificationListView = Backbone.View.extend({
    id: "classification_accordion",
    template: _.template( "<% var classifications = this.options.classifications; _.each(this.collection.attributes, function(v,k) { %>"+
                                        "<h3 class='<%= k %>'><%= classifications.get(k).get('name') %>"+
                                        "<p><%=classifications.get(k).get('menu_desc')%></p></h3>"+
                                        "<% var model = new MenuClassificationList(v); var view = new MenuClassificationItemView({collection:model, classification:k}); %>"+
                                        "<% print(view.render().el.outerHTML); %>"+
                                "<% }); "+
                            "%>"),
    render: function(){
        //console.log(this.options.classifications);
        //console.log(this.collection.attributes);
        //alert(1);
        this.$el.html(this.template());
        return this;

    }

});

How do I incorporate the comparator?

Thanks,
