Isn't -r a GNU extension to sed or something? And you're using a
Sun or a Mac perhaps?

The offending line seems to be

sed -r -e \
"/^ *[cC][rR][oO][sS][sS][rR][eE][fF] *= *[^,]+,?$/d" \
${TMPFILE}.bbl >> ${FINALFILE};

I'm not enough of an RE hacker to know if that really requires -r
or not: try removing the -r and see if it works.
