If the files have the proper rights - the install script can just chmod as needed.
As for changes this could be fixed using checksums for checking modifications, and abort if any were made - as a precaution. People who modify their installation should never run the automatic update anyway and are probably aware of that.
but even if people have modified a file, this may or may not be solvable using diff files instead of complete files.
Currently when updates are as simple as they are this whole ordeal is really insignificant - but once updates gets more hairy like having to extract some files AND run some upgrade scripts it becomes less fun and more prone to errors and updates not being applied.
