That has a typo, you missed out the C. But assuming that's a red herring...

1. Use the pcretest tool which you'll find in the build-xxx directory in
your Exim build.

2. Read the PCRE docs which you'll find in the doc directory in your Exim
build

3. I just tried this:

/(?i)<script>/

Which seems to do the job.
