Hi Denis, in the past, sage-combinat-devel was a very active list and certainly the topic of your post fits well, but it seems to me that it would be a good idea to re-post on sage-devel.
Did you read the developer's guide? Certainly people could help you contributing the code. In particular if the code is written in Python or Cython, it would probably be easy to fit it into src/sage/... Or is it an external package? Then it would of course be nice to have code in the sage library that makes use of the external package. Note that at least in the beginning, a new package would be optional. Concerning the "min" option: At least for now, the old code in Sage would not be removed. So, even with your package installed, one could easily make it so that the old code is used when the user requests the "min" option.
