Unfortunately I dont have any experience with Backburner submissions, since I
have never used it in a pipeline other than submitting to it from a gui.
Here is an example of a preRender script:
In file /network/path/to/myPreRender.mel:
global proc doStuff()
{
// all your preRender Stuff here
}
Then in your render command:
cmdjob -preRender "source /network/path/to/myPreRender.mel; doStuff();"
But from your latest information, it seems you have other problems as well,
such as defining your frame ranges.
Since I again don't know much about backburner I will take a blind stab...

It seems like maybe your string formatting is not correct so it cant slot in
your frame ranges. I assume %tp2 and %tp3
are to be replaced from within backburner, correct? Have you tried NOT escaping
those parts in the string?
' cmdjob -jobName ' + jobName + params + taskListFile + ' -taskName 1 ' \
+ mayaPath + ' -s %tp2 -e %tp3 ' + ' -of png -fnc name.#.ext -pad 3 -im ' \

backburner not properly slotting in your ranges from whatever problem you are
having with your tasklist definition.
That part I unfortunately cant offer any insight.
