MATLAB: How does MATLAB Answers break ties among answers

meta

In a recent question, with no votes for any of the answers, I found some answers jumped around all over the place for no apparent reason while others stayed where they were. How does MATLAB Answers order questions with the same number of votes?

Best Answer

The accepted answer is always listed first.
After that, answers are sorted by the number of votes, then by when the answer was created (oldest-to-newest).
This can cause "jumping" when an older answer is voted up to have the same number of votes as a younger answer. For example:
Answer 2 is listed above answer 1 because it has more votes.
 +--------+-------+---------+
 | Answer | Votes | Created |
 +--------+-------+---------+
 | 2      | 2     | 00:01   |
 +--------+-------+---------+
 | 1      | 1     | 00:00   |
 +--------+-------+---------+
Answer 1 receives a vote, and appears to jump over answer 2 because, even though they now have the same vote count, answer 1 is older.
 +--------+-------+---------+
 | Answer | Votes | Created |
 +--------+-------+---------+
 | 1      | 2     | 00:00   |
 +--------+-------+---------+
 | 2      | 2     | 00:01   |
 +--------+-------+---------+
