as said Randal :

In modern versions of Perl [...] returning either
- a list in a list context,
- or the last element of a list in a scalar context.

(don't forget 'scalar @array' return the lenght of the array)

we are in scalar context, because scalar(@ARGV):

@ARGV = qw(1 2); # scalar(@ARGV) is 2 (number of elements)
scalar qw(2, 3) # is 3, last element of the list => false

@ARGV = qw(1 2); # is 2
scalar(2, 3) # is 3  => false

@ARGV = qw(1 2 3); # is 3
scalar (2, 3) # is 3  => true

@ARGV = qw(1 2 3); # 3
scalar qw(2 3) # is 3 => true

This is the result in perl 5.8 on linux

so the problem seems in the version of perl you are running, if I understand 
the answers from Yitzchak Scott-Thoennes, Jasper McCrea and Stefan Stiasny, 
and obviously Randal.

Thanks for my fwp since I have learned more about perl...
My apologies for my Frenchglish
