At revision 152, there doesn't seem to have any max().

Well it's quite simple. Add a "max" method in main.SelectResults. This
method has to build an SQL expression which is then passed to the
"accumulate" method. In your case the SQL expression would be "MAX(%s)" %
attribute I guess.
Finally to produce the patch, use svn diff :)
