Look at these two tutorials: 

http://www.devdaily.com/blog/post/ruby/ruby-how-sort-array-objects-one-field-column

http://www.devdaily.com/blog/post/ruby/how-sort-ruby-array-objects-multiple-class-fields-attributes

I learned more from reading these two entries than in any book when it came to sorting. In particular, I fell in love with the multi class field sort. I have been able to do some sorting on data that I could have never done otherwise. Walk through the tutorials, if you have an IDE step through the code and watch the array and values that get put into it and experiment with various sorts.
