Thanks a lot Guenni007,

your hint was really helpful. Here is the solution:

To achieve merging your custom .js files with all other .js files you need to do three things:
Go to you parent enfold themes folder:
wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/asset-manager.class.php

On line 242 you will see the following code:

				 if( ('all' == $this->which_files[$file_type] ) || 
				 	('avia-module' == $this->which_files[$file_type] && strpos($file, 'avia-module') !== false ) ||
				 	('avia' == $this->which_files[$file_type] && strpos($file, 'avia') !== false ) ||
				 	( $force_print )) 

This code has a bug, go and change it to:

				// -------------------------------------------------------
				//                   Bugfix - old code
				// -------------------------------------------------------
				// if( ('all' == $this->which_files[$file_type] ) || 
				// 	('avia-module' == $this->which_files[$file_type] && strpos($file, 'avia-module') !== false ) ||
				// 	('avia' == $this->which_files[$file_type] && strpos($file, 'avia') !== false ) ||
				// 	( $force_print )) 
				// -------------------------------------------------------
				//                        new Code
				// -------------------------------------------------------

				if( ('all' == $this->which_files[$file_type] ) || 
					('avia-module' == $this->which_files[$file_type] && strpos($file, 'avia-module') !== false ) ||
					('avia' == $this->which_files[$file_type] && strpos($file, 'avia') !== false ) ||
					( $force_print ) ||
					( in_array( $file, $this->force_include[ $file_type ] ) ))				

				// -------------------------------------------------------
				//                     end of new Code
				// -------------------------------------------------------

After it, go and include your custom.js file in your child-theme functions.php like this:

/** load and merge custom.js with other theme .js files */
function custom_scripts() {
    wp_enqueue_script( 'Child-JS', get_stylesheet_directory_uri().'/js/custom.js', array('jquery'), '1.0', true );
}
add_action( 'wp_enqueue_scripts', 'custom_scripts' );

add_filter('avf_force_include_asset', 'avia_force_include_files', 10, 1);
function avia_force_include_files($force_included) {
    $force_include_js = array('Child-JS');
    $force_included['js'] = array_merge($force_included['js'], $force_include_js);
return $force_included;
}

The last step is to acitvate file-merging of corse:
Enfold Child Theme Options -> Leistung (should be something like performance in EN) -> there:
Enable Javascript file merging and compression

That should do the trick. Again a big thank to Guenni007.
