I tested the script with TL + Miktex. The obvious difference is:

The miktex output starts everywhere like this:

table={
 "G:/Z-Test",

while TL13 output start like this:

table={
 ".",

in both cases a sensible list of font folders follows. 


I also ran
G:\Z-Test>kpsewhich --expand-path=$OPENTYPEFONTS

and can see there the same behaviour: Miktex shows the actual name
of the current folder, while TL shows ".". 

So probably luaotfload doesn't realize that G:\test is the current
folder and so starts to scan the subfolders. Should this problem be
addressed in luaotfload or should miktex change the output of
--expand-path?
