My question is how I should arrange the methods in the module?
There are many ways. I prefer to have my "constructors" (although what commonly is called a constructor isn't really a constructor - Perl has a constructor, and it's called bless) just create and return an object, and nothing else. Initializing the object is just asking for trouble in the long run; specially if you want to use MI.

So, I'd do something like: 

package FruitID;
sub new {bless {}, shift}
sub init {
    my $self = shift;
    ... initialize object ...
}
...
package main;
my $testdata = FruitID->new->init("12 bananas");

Note also that I call new as a class method, and I'm not using indirect calls. That will bite you sooner or later as well, as the call is ambiguous.
