This is just my guess from the outside. The numeric sorting is not a part of the Unicode Collation Algorithm standard, it is an extension by ICU, so one would have to dig into the code or documentation there, but I didn't find anything.
I don't know if there is a way to customize this further to get the effect you want. Maybe you could reach out to an ICU support forum to get more expert insights there.
Ah, thank you for your thoughts. I will reach out to the ICU project as you suggest.
