There may be statistical reasons for it, but that
does not have to be the case. Ordered logit/probit
models are pretty specific models with quite strong
underlying assumptions that are often not met 
(search for Brant test). So my guess would be that 
the people of StataCorp and those users who might 
consider writing such a program as a user written 
program both haven't thought it worth the effort.
But as I said, that is just my guess.
