You can't do it, distutils will automatically set 1.0 or 1.1 depending
on the options you have used. (and not 1.2)
IOW, if you use a PEP 314 field, the DistributionMetadata object
should switch to 1.1.

ALthough, my advice would be to use the new DistributionMetadata class
I have created in distutils2. It's a standalone, PEP 345-compatible
class you can use in your own project. It has a micro-interpreter for
the environment markers described in PEP 345, and also knows how to
read or write 1.1, 1.0 PKG-INFO files.
