Here's a technique to generate non-repetitive random numbers: 

$ perl -Mstrict -Mwarnings -E '
    my @nums = 0 .. 100000;
    say splice @nums, int(rand @nums), 1 for 1 .. 10;
'

Sample output:

10228
67730
84390
58034
22572
34234
43334
38920
5934
82290

Depending on how you want to use this, you may need to check whether @nums becomes exhausted.

The "script" you provided is only a subroutine. You don't show the context in which it is called; you don't show how the global variable $samples is declared or what sort of value(s) are assigned to it. An explanation of the "script" will actually require the script.
