Yes, i think there is some kind of bug in there, either a documentation bug, or implementation bug, or both

perl6form doesn't have an INTeger field, so  {0>>>>>} doesn't mean zero pad (that is only documented for decimal numbers ie floats)

Also, zero padding numeric fields only shows using {]].[[} not {>>.<<} so that could be a doc bug or implementation bug (not implemented, or error not detected)

So to fill that integer field with zeros you have to use lfill right before the value ... this works 

#!/usr/bin/perl --
use strict;
use warnings;
use diagnostics;
use Perl6::Form qw/ form /;

print form 
    { page => { width  => ( 44 + 1), } },
    "{<<{20}<<}|{>>>>>}", 
    "Int for Zero Pad", {lfill => '0',} ,  3 ,
    "{<<{20}<<}|{]]].[[}", 
    "Float for Zero Pad", 3.2,
    "{<<{20}<<}|{]]].[[0}", 
    "Float for Zero Pad", 3.2,
    "{<<{20}<<}|{0]]].[[0}", 
    "Float for Zero Pad", 3.2,
;;;;;
__END__
Int for Zero Pad    |0000003
Float for Zero Pad  |   3.2
Float for Zero Pad  |   3.2000
Float for Zero Pad  |00003.2000

So maybe the implementation is incomplete, doesn't do the padding, or doesn't warn about invalid field pattern .... good job finding this AnaximanderThales
