I'm not sure I understand. Is there something in Cabal or Hackage that
makes date-based numbering schemes not work well?

Yeah, there's not a lot you can do except make the number higher. The
problem is not just hackage, it's all the previous releases in the wild.
All the tools assume the normal ordering on version numbers. Not just
the Cabal/Hackage tools but the native distro tools too.
People have suggested "epochs", but it turns out this doesn't make the
situation any better, as one can never get rid of having to specify the
epoch (eg 1:0.1.1).
