It could be that the scanner profile was built from a scan that was made with some automatic corrections still active, and that something is going on during the scanning process that produces unstable results -- and that for that very reason the profile cannot adequately account for it.
You could go back and review your scanner settings, and make sure that there is no automatic curve or color or tonal adjustment taking place in the scanner software. If you find any, turn them off, and then start the profiling process over again.
And remember that those *very same* settings that you use for the scan from which you have generated your profile will have to be used after the profile has been created. After the scan, you then assign the scanner profile to the scanned image, and from there you convert to your preferred RGB working space. Profiling is based on the premise of a *stable* and *repeatable* device. If any of the scanner software settings or of the device's physical conditions changes, that will invalidate the scanner profile.
