Since a job can have test failures (for several reasons) and is marked as UNSTABLE it should be possible to push tag while it shouldn't if the build fails.
Right now it's only possible to set "pushOnlyIfSuccess" to true/false and therfore tags are pushed if the job fails which is not useful.

It would help, if the option can have options like this:

• UNSTABLE or better
• STABLE
• ("Push anyway" (also if Jobs fails))
