I have a small collection of "handy" korn shell functions one of which fetches tags for a given file. I've made a quick attempt to adapt it to do what you want. It simply does some seding/greping of the (r)log output and lists versions which have ".0." in them (which indicates that it's a branch tag):

get_branch_tags()
{
    typeset FILE_PATH=$1

    TEMP_TAGS_INFO=/tmp/cvsinfo$$

    /usr/local/bin/cvs rlog $FILE_PATH 1>${TEMP_TAGS_INFO} 2>/dev/null

    TEMPTAGS=`sed -n '/symbolic names:/,/keyword substitution:/p' ${TEMP_TAGS_INFO} | grep "\.0\." | cut -d: -f1 | awk '{print $1}'`
    TAGS=`echo $TEMPTAGS | tr ' ' '/'`
    echo ${TAGS:-NONE}
    rm -Rf $TEMP_TAGS_INFO 2>/dev/null 1>&2
}
