My gut feel is that means there is something wrong with the
automounting; it can't tell the difference between devices that appear
before it starts, and those that appear after it starts.

Using blkid feels wrong.  blkid is at a higher level; based on a
library libblkid that works with what the kernel provides.

The order of discovery can be unpredictable, so what is /dev/sdb with
media left connected can be different to what it is when media is not
left connected.

Try to script using the symbolic links created in /dev/disk/by-path
which connect back to /dev/sdb, that way the discovery order is
irrelevant.
