Incorrect %MSRP Discount Icon ??

In table mode, if you click on the up/down sort icon for this column, it sorts from the greatest discount to the least which is very useful. However, the sort icon now shows an Up arrow. But what actually is shown is a decreasing, not increasing, discount. It appears the arrow is indicating the numerical value in ascending order which is opposite of a discount sort in ascending order (most negative number is greatest discount). Could/should the sort icon be changed to a Down arrow the first time you select it?
