I'm seeing an execution time of about 90 seconds under Saxon-EE, down to 23 seconds under Saxon-EE
What baffles me is that with each tail-recursion it takes longer to
execute the function! Do you see this also with 9.4? Any idea about
the possible reason?

Sorry, haven't studied the problem in enough detail to answer this. The 9.3 code is clearly suboptimal, and is fixed in 9.4, which is all I really needed to establish.
