Specifying a warning threshold for a raw value is not possible.

Try "-R 5! -r 5!" and send email through some wrapper script with "-M 
exec SCRIPT". The script could suppress the email if (and only if) the 
message reports a Reallocated_Sector_Ct value below some threshold.

This may work for threshold 100:

#! /bin/sh
n=$(echo "$SMARTD_MESSAGE" | sed -n \
  's,^.* Reallocated_Sector_Ct changed .* to .*\[Raw \([0-9]*\).*$,\1,p')

[ -n "$n" ] && [ "$n" -lt 100 ] && exit 0

exec /usr/bin/mail "$@"
