Even though you are getting the entire file in a variable, the best is to treat it as if an ordinary file and read the file line-by-line and then split the fields as usual.

Code:
#!/usr/bin/perl -w

my $url = 'http://en19.tribalwars.net/map/tribe.txt';
use LWP::Simple;
my $content = get $url;
my @uid;
open(DAT, "<", \$content) or die $!;
while ($line = <DAT>) {
	push(@uid, [split(/,/, $line)]->[1]);
}
close DAT;

use Data::Dumper;
print Dumper(\@uid);

lrange

lrange(n)						       Tcl Built-In Commands							 lrange(n)

__________________________________________________________________________________________________________________________________________________

NAME

       lrange - Return one or more adjacent elements from a list

SYNOPSIS

       lrange list first last
_________________________________________________________________

DESCRIPTION

       List must be a valid Tcl list.  This command will return a new list consisting of elements first through last, inclusive.  The index values |
       first and last are interpreted the same as index values for the command string index, supporting simple index arithmetic and indices  rela- |
       tive to the end of the list.  If first is less than zero, it is treated as if it were zero.  If last is greater than or equal to the number
       of elements in the list, then it is treated as if it were end.  If first is greater than last then an  empty  string  is  returned.   Note:
       "lrange list first first" does not always produce the same result as "lindex list first" (although it often does for simple fields that are
       not enclosed in braces); it does, however, produce exactly the same results as "list [lindex list first]"

EXAMPLES

       Selecting the first two elements:
	      % lrange {a b c d e} 0 1
	      a b

       Selecting the last three elements:
	      % lrange {a b c d e} end-2 end
	      c d e

       Selecting everything except the first and last element:
	      % lrange {a b c d e} 1 end-1
	      b c d

       Selecting a single element with lrange is not the same as doing so with lindex:
	      % set var {some {elements to} select}
	      some {elements to} select
	      % lindex $var 1
	      elements to
	      % lrange $var 1 1
	      {elements to}
