How can I sort a collection in Firebase with Flutter?

Question

I'm trying to display a leaderboard system with Flutter by storing different users' high scores inside of Firebase and I'm having trouble figuring out how to sort the users so only the top 10 show up in the collection that have a score below the user's. So far I got it so it limits it to just the top ten highest scores overall but I can't get it to show the top ten for just the ones that have a score less than the user.

// Get Users stream
Stream<List<HighscoreData>> get score {
    return scoreCollection
        .orderBy('score', descending: true,).limit(5)
        .snapshots()
        .map(_scoreListFromSnapshot);
}
