Rui,
  The answer to your last question is easy--you cannot add a new component 
to an object of class "htest" and have it printed by print.htest. But that 
does not mean that you cannot add a component to the output for your own 
use.
  You will need to decide what you want for output, both visually and in 
terms of ease of any post processing. A data.frame would be nice in that 
it would already for the table for any report, but it would require that 
the test you have designed have the same output for all orders. An 
alternative would be a list that contains the output from each test. 
Printing the list would create a nicely formatted report for each test.
