Perl does not execute Perl inside a Perl string. eg. print "1 + 1"; will output "1 + 1" and not "2". Set up your SQL string properly and it will be fine.

my @tagList = ('red', 'black');
my $sql = 'SELECT table FROM tags WHERE tag IN (' .
    join (', ', map {'?'} @tagList) .
    ')';
my $ID = $dbh->selectall_arrayref ($sql, undef, @tagList);

Update: Fix typo on last line s/taglist/tagList/; I never use camelCase in variable names so it was easy to miss :-)
