I'm afraid that entire script doesn't make too much sense. You may want to run it with the -x(xtrace=) option set to see how and where it fails.
First logical error:COUNT=$(echo "${BACKUPLIST}" | wc -l). Guessing you want that file's line count, try
Otherwise it will just count the file name string, most probably resulting in 1.
Same here START=$(echo "${BACKUPLIST}" | sed -n 1p) and here END=$(echo "${BACKUPLIST}" | sed -n $((1+COUNT-RESTOREPOINTS))p)
If what you're after is to repeat the restores from first to $RESTOREPOINTSth, try to replace by
The terminating fi is missing, but there might be code lines following.
Did you consider the head and tail *nix text tools?

pvm_barrier
BARRIER(3PVM) PVM Version 3.4 BARRIER(3PVM)NAME
pvm_barrier - Blocks the calling process until all processes in a group have called it.
SYNOPSIS
C int info = pvm_barrier( char *group, int count )
Fortran call pvmfbarrier( group, count, info )
PARAMETERS
group Character string group name. The group must exist and the calling process must be a member of the group.
count Integer specifying the number of group members that must call pvm_barrier before they are all released. Though not required, count
is expected to be the total number of members of the specified group.
info Integer status code returned by the routine. Values less than zero indicate an error.
DESCRIPTION
The routine pvm_barrier blocks the calling process until count members of the group have called pvm_barrier. The count argument is
required because processes could be joining the given group after other processes have called pvm_barrier. Thus PVM doesn't know how many
group members to wait for at any given instant. Although count can be set less, it is typically the total number of members of the group.
So the logical function of the pvm_barrier call is to provide a group synchronization. During any given barrier call all participating
group members must call barrier with the same count value. Once a given barrier has been successfully passed, pvm_barrier can be called
again by the same group using the same group name.
If pvm_barrier is successful, info will be 0. If some error occurs then info will be < 0.
EXAMPLES
C:
inum = pvm_joingroup( "worker" );
.
.
info = pvm_barrier( "worker", 5 );
Fortran:
CALL PVMFJOINGROUP( "shakers", INUM )
COUNT = 10
CALL PVMFBARRIER( "shakers", COUNT, INFO )
ERRORS
These error conditions can be returned by pvm_barrier
PvmSysErr
pvmd was not started or has crashed.
PvmBadParam
giving a count < 1.
PvmNoGroup
giving a non-existent group name.
PvmNotInGroup
calling process is not in specified group.
