You're right we should not. I'm the main responsible of this error, I 
beg your pardon !
That's the main reason why we say we are mySQL compliant only for instance.
Hopefully, "replace" should be only found in /admin/ directory.
They was the 1st scripts I did for Koha & in Perl, when starting to be 
involved in Koha, in 2002,january. I agree they are really poor (Perl as 
well as mySQL. But they work correctly...)
