This is exactly the case for which -intreg- was designed for, though
note the point Austin made that it asumes that the unobserved
underlying continuous variable is normally distributed. One thing you
could do is log transform the borders of your intervals. But as I said
earlier today: The results Stata gives you are only as good as the data
you put into it. If the data isn't up to it you'll have to suplement it
with assumptions or get better data.
