Scientists sometimes do publish their software. An example: in Operations Research, the COIN-OR initiative (http://www.coin-or.org http://www.coin-or.org) is a growing set of (Open Source) tools for solving OR problems. Also, in certain disciplines, not only papers, but also the software used to obtain the published result is peer reviewed. For instance, the journal Mathematical Programming Computation (http://www2.isye.gatech.edu/~wcook/mpc/index.html http://www2.isye.gatech.edu/~wcook/mpc/index.html) accepts papers accompanied by the software used by the authors, which is tested and reviewed by technical editors.
