Remove one option from “order by” possibilities

Hi,

It seems, that previously the Woo plugin added different classes the “order by” options, therefore it was easy to remove one option with CSS.

Unfortunately, currently these classes are removed and every possibilities are options.

Please be so kind and let me know, how can I remove only one option (the third)?

Thank you very much!
