It is probably easiest when you download the -parmest- and the
-egenmore- packages from SSC. You do that by typing in Stata

ssc install parmest
ssc install egenmore

The former can be used to create a dataset containing your 
estimates. The latter contain the -axis()- program that you
can use to create an axis variable that is sorted by the
estimates. Below is an example of how to combine those (and
for fun I added confidence intervals...)

*------------------ begin example ------------------------
sysuse nlsw88, clear
logit union married never_married collgrad south

parmest, norestore eform
egen axis= axis(estimate), label(parm)

twoway bar  estimate axis, base(1) horizontal barw(.5) ///
            xline(1) ylab(, valuelabel) ||             ///
       rcap min95 max95 axis, horizontal               ///
            legend(order(1 "point estimate"            ///
                         2 "95% conf. int.") pos(6))   ///
            xtitle("odds ratio") ytitle("")
*-------------------- end example -------------------------

Hope this helps,
