A few decibels is actually a LOT! The difference between 29 db and 32 db means that you would have either too much bass or very weak bass depending on what amp you put on the bottom.
If Erik is correct that gain is not always 100% perfect specification, then the variance might be small. A .7 decibel variance is not that much, but I wouldn't say it's that bad. Speakers are never perfect anyway and actually will vary up to 3-5 decibels through the entire frequency range.
If you put a amp on the woofer that is .7 db higher gain, you might have a "slightly thicker" bass midbass. It's almost like a very slight EQ.
I would ignore those "1.24V" sensitivity numbers. It is just a representation of how much input volts are required to have the amp output a certain amount. The "gain" is the only thing you need to look at.
