with django-graphene==2.1rc1:

class OrderedDjangoFilterConnectionField(DjangoFilterConnectionField):
    @classmethod
    def connection_resolver(cls, resolver, connection, default_manager, max_limit,
                            enforce_first_or_last, filterset_class, filtering_args,
                            root, info, **args):
        filter_kwargs = {k: v for k, v in args.items() if k in filtering_args}
        qs = default_manager.get_queryset() if hasattr(default_manager, 'get_queryset') else default_manager
        qs = filterset_class(data=filter_kwargs, queryset=qs).qs
        order = args.get('orderBy', None)
        if order:
            qs = qs.order_by(*order)
        return super(DjangoFilterConnectionField, cls).connection_resolver(resolver, connection, qs, max_limit,
                                                                           enforce_first_or_last, root, info, **args)

Custom queries need to handle it similarly:

    def resolve_my_todos(self, info, **args):
        user = info.context.user
        if user.is_authenticated:
            qs = Todo.objects.filter(user=user)
            order = args.get('orderBy', None)
            if order:
                qs = qs.order_by(*order)
            return qs
        return Todo.objects.none()

For those looking for a more up-to-date solution, the StackOverflow answer here nicely details the approach (Graphene 2.11.1).
