I don't know of a specific Stata command to do all that at once, but essentially you would just need to estimate the thresholds and rho's from weighted frequencies... so I would imagine you could weight first and then feed the tetrachoric procedure the weighted frequency tables.  As for stratification, I think that would pertain more to standard errors of the rho's, which you could get by bootstrapping.  You may want to see:
