...After the Twitter deals were announced, Bing came out and said, "If someone has a lot of followers, his/her Tweet may get ranked higher. If a tweet is exactly the same as other Tweets, it will get ranked lower."
Google was not as vocal about how it would rank tweets and other real-time results, but the company has now shed a bit of light on that via an interview with MIT's Technology Review. David Talbot interviewed Google "Fellow" Amit Singhal, who has led development of real-time search at the company. According to him, Google also ranks tweets by followers to an extent, but it's not just about how many followers you get. It's about how reputable those followers are.
Singhal likens the system to the well-known Google system of link popularity. Getting good links from reputable sources helps your content in Google, so having followers with that some kind of authority theoretically helps your tweets rank in Google's real-time search...
...Do you commonly use hashtags in your tweets?
If your goal is to rank in Google's real-time search index, you may want to cut down on that practice, because according to Singhal, that is a big red flag for a lower quality tweet. This seems to be part of Google's spam control strategy.
