I would not-so-humbly recommend my module -r2o-, available from ssc:
.ssc describe r2o
" r2o calculates the ordinal explained variation statistic (i.e., R2) described by Lacy (2006), which is used to summarize the fit of a regression model for an ordinal response...."

The measure is documented in:
Lacy, Michael G. 2006. "An Explained Variation Measure for Ordinal Response Models With Comparisons to Other Ordinal R2 Measures." Sociological Methods and Research. 34:469-520.
