Hi Alain!
Sforzato has not been included in the Human Playback Preferences because you have to trick Finale to get it to work. It would only lead to confusion, as it just did with you. Otherwise the HPP for the Special Edition are complete to my knowledge.
For "ord." (which stands for ordinario) I made another home made Technique text, but it was not necessary to include it in the HPP. It then changed back to sustain or detache - depends on the note length. Without it Finale would stay at sforzato. I know that's not very comfortable. That's why it's not included in the original HPP settings for download.
Best,
