Since it’s been a week and there’s no answer at all, I decided to remedy the situation myself. In class-wp-post-comment-rating-settings.php, press Ctrl + F and search for .wppcr_rating:not(:checked) > label {. Simply change the float attribute of this selector to left (if you wanna align this to the left) or keep it at right (if you wanna keep it to the right).

I hope there’s an update for this plugin soon that let’s you add an option to make it float to left or right to make it convenient for people to change their settings at will.

Adding the float option would be great, allowing flexible customization options for users. Hope you will do that. Thanks, once again.
