Your declaration for array and hash are wrong. If you use
warnings you'll see why.
This modified code should do what you want:
#!/usr/bin/perl -w
use strict;
my %hash = (a=>'A', b =>'B'); # parens, not braces
my @array = (1,2,3); # parens, not brakets
my $scalar = 'This is a scalar';
# Pass an array REFERENCE
dummy(array=>\@array, scalar=>$scalar, hash=>{a=>'A', b =>'B'});
dummy(array=>\@array, scalar=>$scalar, hash=>\%hash);
my $hashref = \%hash;
dummy(array=>\@array, scalar=>$scalar, hash=>$hashref);
