Ah- the task prolog is a little interesting:
The task prolog is executed with the same
environment as the user tasks to be initiated.
The standard output of that program is read
and processed as follows:
*export name=value* sets an environment variable for the user task
*unset name* clears an environment variable from the user task
*print ...* writes to the task's standard output.

So what you want is:
#!/bin/bash
echo "export SLURM_DISTRIBUTION=block:block"
Though I've never modified a Slurm environment variable, so there may be
other things at work.
