The sort key doesn't necessarily have to be called score. You can also do { textScore: { $meta: 'textScore' } }, see https://thecodebarbarian.com/2014/04/10/a-nodejs-perspective-on-whats-new-in-mongodb-2-6-part-i-text-search.html .
According to https://www.mongodb.com/docs/manual/reference/operator/aggregation/meta/, { $meta: 'indexKey' } is also valid.
Maybe something like { [key: string]: { $meta: 'textScore' | 'indexKey' } } ?

Good point about the score key. { $meta: 'indexKey' } should be valid but not for sorting, it's just for the projection I think.
