from lfs_criterion_extra.models import Criterion, NumberCriterion

class FooCriterion(NumberCriterion):

    foo = models.IntegerField("Foo"), default=0)

    'may be other model fields'

    value_attr = 'foo'  # from that attribute get value to compare
    content_type = 'foo'  # internal id of the criterion
    name = 'Foo'  # displayable value

    def is_valid(self, request, product=None):
        how_many_foo = product.name.count('foo')
        return self.test_value(how_many_foo)

that`s all, your criterion is appeared in the criterion list.
