After about a week I received a very nice reply from Technorati support [see below]. They fixed the problem, though I do not know exactly what they did.
Note that she included a new [to me] type of query to verify whether your WP categories are being auto-indexed as tags.

I see that query is available under Search/Options.
Hello Steve,
Please accept my apologies for the delay in getting back to you. We’ve been experiencing a backlog in support and are
working hard to address everyone. I’ve taken a look to see if we are successfully indexing your blog. After making a small
adjustment, it looks like all is in order and your blog has been indexed with your most recent posts and tags.

I replied with a new problem, that WP categories were not being indexed. I also received a reply – and that now seems to be fixed also.
So I’ve shifted from unhappy to very happy with Technorati ??
