Note that if you call warnings() on a MARC::Record object the internal list of warnings is cleared, so if you call it a second time for the same object you'll get nothing.

how about in list context?
@warnings = $record->warnings();
This should have been more clear in the docs (which are now updated...in
cvs).
The reason why warnings() returns a list is that a given record could have
multiple warnings. When you assign to a scalar in list context you get the
amount of items in the list, which is why you got a number.
It can be a handy trick sometimes:
my $count = @items; ## number of items in @items
