First, does it really need to be root?

As Matthew Gillen asked, have you set the execute permission on the file? 

Have you tried: 

# sudo /etc/cron.weekly/backup 

(assuming your script is called backup) and does it run? 

I presume you've checked root's email and the system log where cron 
errors get written. 

Also, Matt mentioned paths. Check the cron man page for more information 
on how the environment is set up for programs executed from a crontab. 
Best to use absolute paths, especially for stuff being ran as root.

/bin/sh is the preferred shell for scripts. (Usually linked to bash.)

If you just echo to STDOUT or STDERR, cron will automatically email the 
data to root.

You could rewrite that as: 

cd /usr/local/s3sync && ( 
   echo -e "To: ${EMAIL}\nSubject: s3backup results\nContent-type: 
text/plain\n\n" 
   ../s3sync.rb  ${EXCMDS} --delete -r /etc/ jdata_backup:etc 
   ../s3sync.rb  ${EXCMDS} --delete -r /jdata/ jdata_backup:jdata 
   ../s3sync.rb  ${EXCMDS} --delete -r /home/jmkramer/.tomboy \ 
     jdata_backup:tomboy 
) | ${SENDMAIL} "${EMAIL}"
