you need a binNMU version with +b1 in debian/changelog for seeing the FTBFS.

The VERSION string "0.994-3+b1" is interpreted as arithmetic expression
  0.994 - 3 + b1

A less fatal variant of this bug is already present in the
non-binNMU version in stretch/unstable:
$ scythe --version
scythe version -2.006

scythe.c treating version numbers as floating point is pretty strange.

And due to that, 0003-Get-package-version-from-dpkg-parsechangelog.patch
causes these funny problems.
