Try something like this (not the best example, I find SOAP::Lite quite powerful, but difficult to understand at the same time - untested code).

my $soap;
my $tries = 0;
my $success = 0;
while ($tries < 10 && !$success) {
  $success = 1; # set it to one, on fault, we'll set it to 0
  $soap = SOAP::Lite
    -> on_fault(sub { $success = 0; }),
    -> uri('http...ect');
  ++$tries;
}
