As reported by Simone, when he developed the STACKING logic, he did that
for a specific use case. So the behaviour you are reporting is expected.

The logging you see is reporting the granules found on the folder, which
are added to the mosaic index.
This order depends on how the File.list method returns files after scanning
the folder.
A different thing is the order the granules are returned from the index
when you do a query (as when performing a read operation on a time range).
As an instance, in case granules cover the same region at different times,
you may impose a "sort by time, in descending order" policy in order to get
the youngest granule. You may configure the mosaic layer by setting the
SORTING parameter.
As an instance: *time D*
to ask for queries returning granules sorted by the value of the "time"
attribute of the schema, in *D*escending order

My suggestion was based on the assumption that the STACKing behave
differently. I wasn't aware of/I didn't remember the underlying logic
before checking the code. Therefore, I don't think there is currently a way
to achieve that without doing any code.

Since we are talking about development, an alternative way you may also
consider is developing a process which takes granules from the structured
reader [1] (note the ImageMosaic implements the
StructuredGridCoverageReader) and does the sum you need.
