I still say Sans is the older bother. I'm just saying if Toby told that to the Japanese translators or whatever for the game when asked what Papyrus would call Sans, then I say it's true since they needed to know it. Doesn't matter if it was deleted, that doesn't make it any less of a leg to stand on since it has been seen by many. That tweet from Toby saying that the tweets and kickstarter are not canon I seriously think is a joke. Toby likes to troll. But just looking at the tweets, it's pretty clear to me that it was a joke. You can do what you want, but I think it's pretty clear by now that Sans is the oldest. For more than that reason but I'm not going to list them all. And oldest siblings usually end up being the shortest. Not always but I see it more often than not.
