Sort a Hash by Values routine?

I'm writing a routine that interprets a Log file.
I'm saving the info about browsers in a hash and wish to show the Top-20 Browsers.
Like:    Mozilla/4.77   would be a log entry ,key, for netscape with perhaps the value of '50'.

My dumb problem:
Once I have a hash full of browser names as key, and how many hits for each in values.....what then?  What is an elegant way to find the top-20 ???
