AWS Cloudformation issue installing custom binaries - templates

Question

I'm trying to install a custom compiled package that I have in S3 as a zip file. I added this on my Cloudformation template:
"sources" : {
"/opt" : "https://s3.amazonaws.com/mybucket/installers/myapp-3.2.1.zip"
},
It downloads and unzip it on /opt without issues, but all the "executables" files don't have the "x" permission. I mean "-rw-r--r-- 1 root root 220378 Dec 4 18:23 myapp".
If I download the zip and unzip it in any directory, the permissions are Ok.
I already read the Cloudformation documentation and there is no clue there.
Someone can help me figuring this out? Thanks in advance.

Maybe you can combine a "configSets" (to guarantee the execution order) and a "command" element to write something like :
"AWS::CloudFormation::Init" : {
"configSets" : {
"default" : [ "download", "fixPermissions" ]
},
"download" : {
"sources" : {
"/opt" : "https://s3.amazonaws.com/mybucket/installers/myapp-3.2.1.zip"
},
},
"fixPermissions" : {
"commands" : {
"fixMyAppPermissions" : {
"command" : "chmod +x /opt/myapp-3.2.1/myapp"
}
}
}
}
