We found that the backslashes need to be escaped, as in:

%global revision %(echo %{version} | sed 's/^.*\.\([^.]*\)$/\1/g')

This always takes the last component of the version. Alternatively, this also
works, assuming that the version has 3 components (it always takes the 3rd
component):

%global revision %(echo %{version} | cut -d. -f3)
