It is because you use single quotation marks when passing ${USE_FACILITY} into
regular expression substitutions string, so the shell doesn't invoke subshell to
substitute `blabla blabla`, but instead pass it as-is:

@${PERL} -pi.fbsd -e 's.!!USE_FACILITY!!.${USE_FACILITY}.g'

Use the following instead:

@${PERL} -pi.fbsd -e "s.!!USE_FACILITY!!.${USE_FACILITY}.g"
