It is easy to see your answers and questions from the user interface.
It is not easy to see your old comments.
Is it a way to do so? if no, shouldn't it?
You can see your comments on your activity tab: https://tex.stackexchange.com/users/28474/ppr?tab=activity&sort=comments - this is not as sophisticated as views on Qs and As, because you can only see them ordered from newest to oldest, but they should all be there.
Use this site for viewing all your comments sorted by their score.
Input your user ID (hint: what is my user id?)
Enter "TeX" in the input box saying "search by name or url"
However, StackExchange kindly provides the StackExchange Data Explorer which lets you run custom SQL queries against their data sources.
Here is a simple query I made, which shows all your comments sorted by their votes: http://data.stackexchange.com/stackoverflow/query/155827/find-all-comments-ordered-by-votes
