I wouldn't be too concerned about it being suddenly harder to get a passing score. If the exams remain valid, then your performance under then new scoring should be similar to your performance under the old scoring.

I would be quite concerned, though, about the new scoring in general. Has it been evaluated by ACE? Has it been evaluated and approved by Excelsior, TESC, COSC, and other schools? I'm very glad this didn't happen a few months ago, as I predict some delays in getting credit for these DSST exams. I'm not calling for panic -- my guess is that the approvals and credits will eventually come through, and I don't think anybody is going to have to re-take an exam -- but I do predict delays. We'll see if I'm right, or if that's just my streak of pessimism.
