I am unable to reproduce this. I tested the script under Inquisit 3, and I get accurate feedback.

I am unable to reproduce this under Inquisit 3 as well. The script runs properly, i.e. doesn't stop after a single trial for me, but instead increases or decreases difficulty as intended.
I suspect you may be using an extremely outdated Inquisit 3 version. You _should_ be using version 126.96.36.199, which you can download via the archives at https://www.millisecond.com/download/archives.aspx
