For such question, there is data.SE. Apparently, someone thought about it too, so there is a query for this badge. I let you run it with your user id and on the right site. I suppose you can search on data.SE for any badge, someone probably wrote a query for it.
As you mentioned, the query did not order the comments as one can expect. I clicked on the column to sort it as I wished. But a better way is I forked the query and edited it for the right purpose: here you can see your sorted comments. Feel free to fork it and customize it as you like, the language is standard or close to standard SQL, and the tables are described on the right panel.
Good luck catching the badge, apparently you're on the right track!
