I think it was a misunderstanding as think he mentioned association not necessarily difference; but am not sure, maybe he has said difference in another post.

Btw, I too agree that chi-square or dichotomizing the 6 levels (for a Fisher) were also practical, good solutions. But once I faced a similar design, and after some trials I thought that correlation test might be the best option because it maintains a higher power (I think) than a chi-square with many cells less than 5, and also doesn't loose data by collapsing the groups.
