"sort cannot be used with count" in 3.9.3

Almost the same problem as in #1950, but now sort crashes with "sort cannot be used with count" after count.

For example, this code (coffescript) works:

mongoQuery = this.findAll(query, null, options, fields);
mongoQuery.sort(_id: -1);

async.parallel({
    count: function (next) {
        mongoQuery.count(next);
    },
    data: function (next) {
        mongoQuery
            .limit(limit)
            .skip((page - 1) * limit)
            .exec(next);
    }
}, cb)

But this one (sort moved to data function in async.parallel and seems like called after count) - don't:

mongoQuery = this.findAll(query, null, options, fields);

async.parallel({
    count: function (next) {
        mongoQuery.count(next);
    },
    data: function (next) {
        mongoQuery
            .sort(_id: -1)
            .limit(limit)
            .skip((page - 1) * limit)
            .exec(next);
    }
}, cb)

As I mentioned, I think there are the same problem as in issue #1950, because Query.prototype.sort still using mquery and wasn't rewrote like Query.prototype.count in this commit.

Thanks for pointing this out, I'll fix it.
