There is a section in the Bash man-page, which goes some way to explaining your predicament (the same also holds of other shells which support job control, but man ksh doesn't word it quite like that):

Code:
COMMAND EXECUTION ENVIRONMENT
       The shell has an execution environment, which consists of the following:

       o ....

       o ....
...
       o      various process IDs, including those of background jobs, the value of $$, and the value of $PPID

That's to say that jobs won't show you background processes started in your shell from your script (which runs in a different environment from your shell).

Your best bet, if it's practicable, is to run your script in the same environment as the shell which started the jobs.

i.e.
Code:
$ . ./myscript

or to pass the jobs PID's into the script, i.e, like
Code:
./myscript $(jobs -p)

myscript:
Code:
for job in $@; do
  echo $job
done

qorder(1B)								PBS								qorder(1B)

NAME
qorder - exchange order of two pbs batch jobs in a queue. SYNOPSIS
qorder job_identifier job_identifier DESCRIPTION
To order two jobs is to exchange the jobs positions in the queue or queues in which the jobs resides. The two jobs must be located at the same server. No attribute of the job, such as priority is changed. The impact of interchanging the order with the queue(s) is dependent on local job scheduled policy, contact your systems administrator. A job in the running state cannot be reordered. OPERANDS
Both operands are job_identifiers which specify the jobs to be exchanged. The qorder command accepts two job_identifier operands of the form: sequence_number[.server_name][@server] The server specification for the two jobs must agree as to the current location of the two job IDs. STANDARD ERROR
The qorder command will write diagnostic messages to standard error for each error occurrence. EXIT STATUS
Upon successful processing of all the operands presented to the qorder command, the exit status will be a value of zero. If the qorder command fails to process any operand, the command exits with a value greater than zero. SEE ALSO
