While they're stored as integers, some of the database adaptors return
everything as strings. This would seem to be borne out by the concatenation.
Try:
<dtml-let total="_.int(SUNDAY) + _.int(MONDAY) + _.int(TUESDAY) +
_.int(WEDNESDAY) + _.int(THURSDAY) + _.int(FRIDAY) + _.int(SATURDAY)">
to explicitly convert your results to integers.
