You have the write code to select a single random element from the array. To get unique random numbers, you need to remove that element from the array and then keep selecting from the shorter set. splice lets you do this in one operation. 
my @num;
my @array = 1 .. 10;
for (1..3) {
    push @num, splice(@array, rand(@array), 1);
}
