Judging from this crosstable, I’d say that tied players are listed in order of post-tournament ratings, rather than pre-tournament ratings as I had always assumed.
No biggie, just a curiosity. Nolan has probably covered this topic many times in many posts, and I just missed it.

I think its actually by overall likability. 
Thank you for the compliment, but I also like the person who was listed after me (higher-rated than me in every category except post-tournament regular rating).

It uses post-tournament ratings because pre-tournament ratings can produce confusing ordering for those who have no pre-tournament rating. (We don’t show it on MSA, but we have their estimated rating in the pre-tournament rating field.)
Makes sense.
