I only have a few seeds left. Can anyone suggest a technique? Does mechanical scarification help? Or is it likely that these seeds are just duds?

I haven't grown this but I've been to similar habitat. It's not like what most people think of as a succulent desert Agave, rather more like a tuberose (which is also now called Agave.)

Based on reported flowering periods it is possible some seed ripens while it is still raining, which begins approximately in early May, and some after rain is finished for the year, which is approximately early October. That means at least some seed would have a very long cool to slightly frosty and dry winter rest before the next growing season.

I don't know how long it is viable, and you might not be able to find out when yours was harvested. But I would consider putting it dry into the refrigerator for a few months, then trying again with hot and moist conditions.
