As many of you are certainly aware, RPM 4.13.0 brought, amongst
other
things, the ability to use file triggers (i.e. run a script
whenever a
package installs/removes a file to a specific directory)
"a script" as in a single, global script per "file"?
Or rather "at least one script" per "file"?
In case of the latter: what defines the ordering?
Would a pkg B be able to override the system provided pkg A?
'a script' is an rpm scriptlet - defined in the .spec file (as were
%post scripts)

The file trigger is defined 'per location to be monitored'

The script is started 'once per package that installed files' (in case
of filetriggerpost) - and gets the file list as input (so it can do
something out of it)

The rpm scriptlet can have a weight - which could define the order in
case more than one file trigger hits (so far I did not see a need for
this and the 4 triggers implemented are all the same weight)

For the interested ones, the rpm documentation can be a worthy read:
