We have Item UDAs setup that we are referencing in Pricing attribute based rule within Discount list setup.

Within discount list, we have attribute based rule that are using the Item UDAs.

 

Now when we enter the rows each with different combination of UDAs, we notice the pricing engine starts evaluating from top row and if a match found it applies that discount percent. 

But when we have multiple rows entered , system is rearranging the rows randomly making some row at the top which we kept in the middle while entering.
