Now that you mention it - [1].
A mirror can override a package priority, that's true.
I don't know if http://ftp.debian.org/debian/indices/ is mirrored too,
along with the usual Release files and *debs. It can explain this
discrepancy if it's true.
The question is - which Priority goes into the package database on
package install? That one from the package itself, or the one from the
mirror?

It sure did not happen here.

In the context of the original deboostrap behaviour - it's simple.
debootstrap installs barebones to produce a working apt, and uses it to
install the rest of the packages.
apt trusts the mirror (it would be counterproductive to download and
analyze every package just to extract their Priority and Depends), hence
mirror's priority wins here.
