I thought code written for science papers was generally crap (from a maintenance/review perspective, because the people who write it are scientists first and programmers second), and often not published anyway? The idea behind not publishing being that if someone tries to reproduce your work, it's best to make certain the won't reproduce your coding bugs by copying (and also that publishing crap code is embarrassing)...
