Gene,

Asking for a "permutation approach" is redundant to what has been posted.  The
so-called Exact-test approach is permutation, for which we use randomization when the
permutation-universe is too large. 

As you say, it does not address ordinality; it only seeks to replace the overall contingency
chi-squared (for which the power is small).

What I was trying to say about the permutation tests:  They need to order the outcomes;
when the table is larger than 2x2, there are several competing criteria for "order" that do
not necessarily give the same order.

The only thing it would do is to say that the observed test value is at the 'x' percentile of the distribution of test values resulting from all permutations of the dataset. Gene Maguin
