Yes, you can change the order of the products. on your product results page on line 155 of the line that starts with $query_WADAProducts, change where it says:
= ProductID at the end of the line to:
= ProductID Order By ProductUpdateDate DESC
this will order by the date field, but remember that if you make update an old product, then it will become the new one. You could also change this to say:
= ProductID Order By ProductSKU DESC
