One way would be to build up the prefix in an ACL variable.
# 1 - for SPF:
# add this to subject
set acl_m_subj_prefix = $acl_m_subj_prefix *** SPF Error ***
# 2 - for SPAM:
# add this to subject
set acl_m_subj_prefix = $acl_m_subj_prefix ***SPAM (score: $spam_score)***
warn
condition = ${if!eq{}{$acl_m_subj_prefix}}
logwrite = subject rewritten
# remove old subject
remove_header=Subject
# create a new subject
add_header = Subject: $acl_m_subj_prefix $h_Subject:
# discard the variable
set acl_m_subj_prefix =

If your exim configuration supports UTF-8, then yes.
