The priority in front of each package (500 or 100 in the example above) is the priority advertised by the package in that repository or location. The number at the end (namely 991) is the actual pin priority being placed on the package. This is like a critical threshold that has to be surpassed for a package to be considered a candidate for installation.

The package with newer version number 8.4.3 is ignored because its priority (500) is lower than the pin priority (991).
