It looks like that in one of the pairs, 1 is being treated as key, not a value. Perhaps the param subroutine is returning multiple elements and confusing the ordering.

By contrast, the following works just fine on my system:

use Data::Dumper;

my $userInfo;
my $number = 1;
my $temp = 1;
push @$userInfo, { number => $number,
    name => 'param',
    id => 'param',
    rollSizzle => 'param',
    roll => $temp,
    sizzle => $temp} ;
print Dumper($userInfo);
