Generally: yes, status != 0 is sufficient, if I can be sure that status 0 isn't the only code returned, and without any documentation I assume the worst (I've seen too many tools always returning 0, no matter what).
But, knowing the operators that will have to use that script, sooner or later I'll have to give more information than just Success/Failure, and I'd rather get that information via a return code, that by parsing the command output, which could change without warning.
Besides, I'm sure I'm sooner or later someone will have a similar task, where the scripts execution path will depend on the failure reason.

pvmftasks
TASKS(3PVM) PVM Version 3.4 TASKS(3PVM)
NAME
pvm_tasks - Returns information about the tasks running on the virtual machine.
SYNOPSIS
C int info = pvm_tasks( int where, int *ntask, struct pvmtaskinfo **taskp )
struct pvmtaskinfo {
int ti_tid;
int ti_ptid;
int ti_host;
int ti_flag;
char *ti_a_out;
} taskp;
Fortran call pvmftasks( where, ntask, tid, ptid, dtid, flag, aout, info )
PARAMETERS
where Integer specifying what tasks to return information about. The options are:
0 for all the tasks on the virtual machine
pvmd tid for all tasks on a given host
tid for a specific task
ntask Integer returning the number of tasks being reported on.
taskp Returns pointer to an array of structures which contain information about each task including its task ID, parent tid, pvmd task
ID, status flag, and the name of this task's executable file. The status flag values are: waiting for a message, waiting for the
pvmd, and running.
tid Integer returning task ID of one task
ptid Integer returning parent task ID
dtid Integer returning pvmd task ID of host task is on.
flag Integer returning status of task
aout Character string returning the name of spawned task. Manually started tasks return blank.
info Integer status code returned by the routine. Values less than zero indicate an error.
DESCRIPTION
The routine pvm_tasks returns information about tasks presently running on the virtual machine. The information returned is the same as
that available from the console command ps. The C function returns information about the entire virtual machine in one call. The Fortran
function returns information about one task per call and cycles through all the tasks. Thus, if where = 0, and pvmftasks is called ntask
times, all tasks will be represented.
Note that in Fortran the reported value of ntask and the set of tasks do not change until the function resets at the end of a complete
cycle. The user can reset pvmftasks() at any time by calling it with ntask = -1.
If pvm_tasks is successful, info will be 0. If some error occurs then info will be < 0.
EXAMPLES
C:
struct pvmtaskinfo *taskp;
int i, ntask;
info = pvm_tasks( 0, &ntask, &taskp );
for (i = 0; i < ntask; i++)
printf("t%x
", taskp[i].ti_tid);
Fortran:
Do i=1, NTASK
CALL PVMFTASKS( DTID, NTASK, TID(i), PTID(i), DTID(i),
& FLAG(i), AOUT(i), INFO )
EndDo
ERRORS
The following error condition can be returned by pvm_tasks
PvmBadParam
invalid value for where argument.
PvmSysErr
pvmd not responding.
PvmNoHost
specified host not in virtual machine.
