You need to define the appropriate csv.QOUTES type. You probably have
csv.QOUTES_MINIMAL (which is the web2py default)

Try the following

import csv
db(query).select().export_to_csv_file(s, delimiter=',', quotechar='"',
quoting=csv.QUOTE_NONNUMERIC)
db.import_from_csv_file(s, delimiter=',', quotechar='"',
qouting=csv.QOUTE_NONNUMERIC)
