sort bug

Dear Basex team, it seems to me that there is a little bug in the FLWOR sort. Code:

for $i in 1 to 3
for $j in ('a', 'b', 'c')
order by $i descending
return
   concat($i, $j)

Expected output: 3a 3b 3c 2a 2b 2c 1a 1b 1c Actual output: 3c 3b 3a 2a 2b 2c 1c 1b 1a Using the latest stable snapshot. Kind regards, Hans-Juergen
