Thanks to Kit Baum, two new packages for ordinal response variables are available from SSC.

1) ?ordvar- calculates several related measures of dispersion and consensus for ordinal variables, along with standard errors for them.
To install, type -ssc install ordvar-

2) ?r2o- calculates an explained variation fit measure for ordinal response models. To install, type ?ssc install r2o-.

Both packages treat ordinal variables without assumptions about inter-category distances. ?r2o- requires no assumption of a particular distributional form, method of estimation, or type of response model. The measures implemented in these packages are documented in published work, cited in their respective help files.
