How can I combine two very good ideas together?

I got two scripts

both function: find-change on master

I love both very mcuh

but how can combine two scripts together?

1st:

//---------------------------------------------------------------------------------------- ----------------------------

if ( app.documents.length > 0 ) {

    if ( app.scriptPreferences.version >= 6 ) {

        app.doScript( main, ScriptLanguage.JAVASCRIPT , [], UndoModes.ENTIRE_SCRIPT, "Search in masterpages" );        

    }

    else {

        main();

    }

} else {

    alert ( "No documents open!" );

}

function main() {

    // Your settings

    // ---

    var searchList = [

        [ "USA" , "Obama" ],

        [ "rocket" , "sky" ],

        [ "New York" , "Los Angeles" ]

    ];

    app.findGrepPreferences = app.changeGrepPreferences = null;

    app.findChangeGrepOptions.includeMasterPages = true;

    var target = app.documents.everyItem().masterSpreads.everyItem().textFrames.everyItem();

    for ( var j = 0; j < searchList.length; j++ ) {

        var curSearch = searchList[j];

        app.findGrepPreferences.findWhat = curSearch[0]; 

        app.changeGrepPreferences.changeTo= curSearch[1]; 

        target.changeGrep(); 

    }    

    app.findGrepPreferences = app.changeGrepPreferences = null;

} // main

2nd:

//---------------------------------------------------------------------------------------- -------------------------------

var myDocuments = app.documents.everyItem();
var myLayers = myDocuments.layers.everyItem();

//Locked text frames on master spreads are not touched.
//If you want to unlock them you have to add something like this:

//Unlock ALL page items in every document on spreads and master spreads (optional):
myDocuments.pageItems.everyItem().locked = false;

var myPageItemsOnNormalSpreads = myDocuments.spreads.everyItem().pageItems.everyItem();

//Unlock the layers (optional)
myLayers.locked = false;

//Lock all first level page items on normal spreads
//That leaves the page items on master spreads unlocked:
myPageItemsOnNormalSpreads.locked = true;

//Now for the GREP part:
app.findChangeGrepOptions.includeMasterPages = true;
app.findGrepPreferences = changeGrepPreferences = null;
app.findGrepPreferences.findWhat = "\\b20\\d+\\b";

//Do the search on "all open document" level
//That will return an array of arrays:
var myTarget = myDocuments.findGrep();

//Flattening the myTarget array:
var flattenedFoundArray = [];

for(var n=0;n<myTarget.length;n++){
    flattenedFoundArray = flattenedFoundArray.concat(myTarget[n]);
    };

//Change contents of found texts in flattened array:
for(var n=flattenedFoundArray.length-1;n>=0;n--){
    flattenedFoundArray[n].contents = String(Number(flattenedFoundArray[n].contents) + 1);
    };

//Unlock all objects on normal spreads:
myPageItemsOnNormalSpreads.locked = false;

//Reset GREP find and change prefs:
app.findGrepPreferences = changeGrepPreferences = null;
