wpDiscuz comment list can be ordered by "Newest", "Oldest" and "Most voted" comments.
By default, comments are sorted by the newest comments (new comments on top). This is based on the according WordPress native discussions setting.
If you want to change the ordering, just navigate to Dashboard > Settings > Discussions admin page, and change the value of the "Comments should be displayed with the newer/older comments at the top of each page" option.
More info here: https://wpdiscuz.com/docs/wpdiscuz-7/plugin-settings/comment-thread-displaying/#display-comment-sorting-options
wpDiscuz also allows you to set the "Most voted" comment order by default. The option calls "Set comments order to “Most voted” by default". It's located in the Dashboard > wpDiscuz > Settings > Comment Thread Displaying admin page.
