I usually use the following code lines: 
package My::Module;
use Getopt::Long;
sub process {
    local @ARGV = @_;
    # handle command line or named parameter options:
    GetOptions(...) or die ...;
    # here follows the rest of the script
}

return 1 if caller;

# This is executed only in "script" mode:
process(@ARGV);

# In "module" mode I have to write:
#   use My::Module;
#   My::Module::process(-bla => "foo", ...)

Of course there are variations of these scheme possible --- you just need the "return 1 if caller" line to distinguish between module code and script-only code.
