Listing Order Bug

Description

Report by user:

I have used the following Listing Order for taxonomy

Clause 1: Top Rating (decending)
Clause 2: Review Count (decending)
Clause 3: Random

However, the 2nd clause does not appear to be working correctly, as currently a listing with 1 review is appearing higher than a listing with 21 reviews (both are 5 overall stars). This is because the listing with 21 reviews has a few reviews with 4 stars (but overall average is 5 so appears to users as 5)

Is it possible for the clause to only use whole numbers for the average star rating?
As it currently doesn’t make sense to the user for a listing that ‘appears to have 5 stars and 21 reviews, to be lower than another with one 5 star review
