Subject: Accessing Hash elements in sorted order?

Problem: I wanted to access the elements of a Hash (specifically from 
CGI#params) in sorted order.

My resolution: Hash#sort returns an array which can be accessed via 
Array#each, but each item is another array.  So the return of 
CGI.param.sort is:

[[key1,value1],[key2,value2],[key3,value3],...,[keyn,valuen]]

So I wrote (essentially -- the meat):

cgi = CGI.new
cgi.params.sort.each { |pair| puts "#{pair[0]}=#{pair[1]}" }

Is this *really* the best way to access the elements of Hash in sorted 
order?  I suppose, if at base, this is the way to do it, I could extend 
Hash to abstract this...
