[Dovecot] Possible pigeonhole dealing with negative numerical values

Using dovecot 2.2.9 and pigeonhole 0.4.2
The system is a Xen VM running Arch Linux x86_64, presently up to date,
on an XFS filesystem in an LVM2 partition. After recently updating my
mail server, I found that a sieve rule I had which would check
X-Spam-Score for a value over a certain number, in my case 2.5. In my
most recent update, negative values would trip the rule.
Here's the rule in question:
# rule:[Spam Filter Subject]
if anyof (header :contains "Subject" "[SPAM]", header :value "gt"
:comparator "i;as
cii-numeric" "X-Spam-Score" "2.5")
{
fileinto "Spam Box";
stop;
}
I have a successful work-around by checking the numerical value and also
insuring that the header doesn't contain a '-', and things work as they
should. Possible the bug could be in my Sieve interface, which is a
RoundCube plugin. Otherwise things are working great.
If there's anything I can add, please let me know. Thanks!
