However, if I switch the image to 3.11.6, it works fine...
What's going on here? 3.11 used to work, and we'd prefer to keep that tag for image stability purposes.

@cpitstick-argo your provided Dockerfile works fine on my end, maybe 3.11 is stable again ? @sudoii I have what maybe a similar issue with the following Dockerfile:
FROM alpine:3.12
RUN apk --no-cache add python
Producing:
ERROR: unsatisfiable constraints:
python (missing):
required by: world[python]
The command '/bin/sh -c apk --no-cache add python' returned a non-zero code: 1
Current fix: Staying in 3.11 works fine, so fixing both major and minor does the trick
I wonder if the issue is linked to https://github.com/pypa/packaging/issues/308
@cpitstick-argo yeah, I have no issue with your provided Dockerfile for 3.12, 3.11 succeed too but seems to silently skip pip3 install:

The silent skipping of the pip install for 3.11 is the problem.
It is not silently skipped. python3 provides py3-pip so apk add py3-pip will install python3
$ docker run --rm -it alpine:3.11 sh -c "apk update -q && apk info --provides python3"
python3-3.8.2-r0 provides:
py3-pip
...
...
ERROR: unsatisfiable constraints: python (missing): required by: world[python] The command '/bin/sh -c apk --no-cache add python' returned a non-zero code: 1
This is because we've stopped providing the python package for 3.12: http://dup.pw/alpine/aports/5ad0ec7d
Please explicitly install python2 if you still need python2, or install python3 if you need python3
