Since it takes an argument the filter needs to be dynamic.

The parser doesn't allow FILTER to be mixed inside expressions.
This will be fixed in v3.

Instead of a filter you can add your own SCALAR_OPS to the Stash, eg:
use Template;
sub sprintfTT {
my ($str, $format, @extra) = @_;
return sprintf $format, $str, @extra;
};
$Template::Stash::SCALAR_OPS = {
'sprintf' => \&sprintfTT,
};
my $tt = Template->new();
$tt->process(\*DATA) || die $tt->error();
__DATA__
[% x = 3.141; x.sprintf("%10.5f"); %]
[% y = 1.618; y.sprintf("y = %.5f, x = %.5f", x); %]
