my($text2) = "test_\1_\2_\3";

In the line above, the backslashes are being interpolated since they are in double quotes. To avoid the interpolation, modify it like:

my($text2) = 'test_\1_\2_\3';  # Single-quotes don't interpolate

or

my($text2) = "test_\\1_\\2_\\3"; # Escaping the backslashes

As for the beginning portion, you might want to use Data::Dumper to verify that $GenEnt is really holding what you think it is. That would be my first step in debugging the problem.
