Is it possible to do an operation on a found digit in indesign?

Question

Basically I need to increase every digit in bold underline(bold underline for emphasis, not in original document) in the text below (just an example of much larger document) by 1 and I'm hoping there's some GREP or plug-in way to do it. If anyone has any ideas outside of indesign, I'm open to them too (word or excel etc!). Thanks in advance! Title Page Copyright Table of Contents Prologue

I'm such a ditz at times
You want to increase by 1 like playorder 1 becomes playorder 2 -------- sigh I thought just meant in size or something.

This has come up before and I have a similar script so have something here that works.

(function () {
    if (app.documents.length === 0) {
        alert("No document open.");
        return;
    }

    var doc = app.activeDocument;
    app.findGrepPreferences = NothingEnum.nothing;
    app.changeGrepPreferences = NothingEnum.nothing;

    // Match only numbers within playOrder="###"
    app.findGrepPreferences.findWhat = '(?<=playOrder=")\\d+(?=")';

    var results = doc.findGrep();
    if (results.length === 0) {
        alert("No playOrder numbers found.");
        return;
    }

    for (var i = 0; i < results.length; i++) {
        var num = parseInt(results[i].contents, 10);
        if (!isNaN(num)) {
            results[i].contents = (num + 1).toString();
        }
    }

    alert("All playOrder values have been increased by 1.");

    app.findGrepPreferences = NothingEnum.nothing;
    app.changeGrepPreferences = NothingEnum.nothing;
})();

You beat me to it @Eugene Tyson I used exactly the same grep—great minds think alike! &#128578; Here's a demo document to help.- Mark
