Today I rerun all test with values from 0.0 to 10.9, everything is working fine (starting from value 5.6 the rule begun to work). I can't reproduce yesterday's triggering, either with "6" or "6.0". Seemed I'm done something wrong.
Sorry for the noise.

Test case: /root/ive/sieve-spamteset.svtest:
1: Test 'Value: 3.6' SUCCEEDED
2: Test 'Value: 3.8' SUCCEEDED
3: Test 'Value: 5.9' SUCCEEDED
4: Test 'Value: 6.0' SUCCEEDED
5: Test 'Value: 6.9' SUCCEEDED
6: Test 'Value: 7.3' SUCCEEDED
PASS: 6 tests succeeded.

Thanks for clarifications.
