This is the best solution we've found for affordable fraud screening. It does take time to configure rules, and the initial limitation of 5 rules is not very useful. 10 rules for us allows good automatic screening. The score number is helpful, we find that we can trust the low (safe) scores very well, but the high (risky) scores have a fair number of false positives. That's a good situation, really.
