The upgrade script looks for the tables based on your table prefix you have entered in the reviewpost config-inc.php file.
Code:
Content visible to verified customers only.
I have not encountered any 1.02 reviewpost sites but that was before my time with the company so can't say but looking at line 214 of the script I see this and note the change I made in bold
Code:
Content visible to verified customers only.
Now your upgrade should go smoothly just run each step ONLY ONCE and make sure before you begin to take a backup of your database cause the last upgrade changes the file structures and all so make sure you have a backup in case you run it twice by mistake etc.
