 Part of this may come back down to "file"...

pi@rpi3bplus-1:~$ file -k -r  *.py
test1.py: Python script text executable Python script, ASCII text
executable
-
test2.py: Python script text executable
- a /usr/bin/python3 script text executable Python script, ASCII text
executable
-
tst.py:   ASCII text
-
pi@rpi3bplus-1:~$


 Note how all three have the tag "ASCII text"... That likely triggers
any application that handles "text/plain".

 As for Geany -- since you manage to have file return text/x-python3 for
some files, you may have to add that to the geany.desktop to get it to show
for those files.

 I suspect you can't reorder the list -- it's either alphabetical (based
upon some field in the .desktop file) or it's the order the .desktop files
were scanned when building the menu.
