Omen of putrefication causes incorrect trade site sorting

Incorrect sorting occurs in trade results when trying to sort by modifier magnitude. clicking on a non-desecrated modifier will cause the results to sort properly, with desecrated and normal mods mixed together, in descending magnitude. However, if a desecrated modifier is clicked for sorting, the site will sort by only desecrated modifiers, and items with matching normal mods come after all of the items with desecrated modifiers, regardless of magnitude.

An example, with made up items:
Jewel 1 20% max energy shield (normal)
Jewel 2 19% max energy shield (desecrated)
Jewel 3 18% max energy shield (normal)
Jewel 4 17% max energy shield (desecrated)

Clicking on max energy shield mod of Jewel 1 to sort descending results in:
Jewel 1
Jewel 2
Jewel 3
Jewel 4

Clicking on max energy shield mod of Jewel 2 to sort descending results in:
Jewel 2
Jewel 4
Jewel 3
Jewel 1 (not sure about 1 & 3, its probably by price rather than modifier magnitude)
