SortParagraphs (not working)

Hi @uniq1, here is a little script I wrote to handle your example. It works by padding out the numbers with zeros and sorting that. Select the text or text frame and run script. Let me know how it works for you.

function main() {

    sortParagraphsByPaddingNumbers(app.activeDocument.selection[0]);


    /**

    function sortParagraphsByPaddingNumbers(items) {

        if (!items.hasOwnProperty('paragraphs')) {
            alert('Please select some text or a text frame and try again.')
            return;
        }

        // add a carriage return if necessary
        if (items.paragraphs.item(-1).characters.item(-1).contents != '\u000D')
            items.paragraphs.item(-1).insertionPoints.item(-1).contents = '\u000D';

        var paragraphs = items.paragraphs.everyItem().getElements(),
            sorter = [],
            afterPoint = items.paragraphs[paragraphs.length - 1].insertionPoints[-1];

        // make a sortable version of each paragraph
        for (var i = 0; i < paragraphs.length; i++) {

            var parts = paragraphs[i].contents

                // remove carriage returns, linefeeds
                .replace(/[\u000D\u000A]/g, '')

                // separate numbers
                .split(/(\d+)/g);

            // make a sortable string out of the parts
            // by padding the numbers with zeros
            for (var j = 0; j < parts.length; j++)
                if (!isNaN(Number(parts[j])))
                    parts[j] = ('0000000000' + parts[j]).slice(-10);

            // combine into a handy object
            sorter[i] = {
                paragraph: paragraphs[i],
                sortable: parts.join('')
            };

        }

        // sort using the sortable string
        sorter.sort(function (a, b) {
            if (a.sortable > b.sortable) return 1;
            else if (a.sortable < b.sortable) return -1;
            else return 0
        });

        // duplicate paragraphs in sorted order
        for (var i = 0; i < sorter.length; i++)
            resolve(sorter[i].paragraph.toSpecifier()).duplicate(LocationOptions.AFTER, afterPoint);

        // remove the unsorted paragraphs
        for (var i = paragraphs.length - 1; i >= 0; i--)
            resolve(paragraphs[i].toSpecifier()).remove();

        function isNaN(n) {
            return n !== n;
        }
    }


}

app.doScript(
    main,
    ScriptLanguage.JAVASCRIPT,
    undefined,
    UndoModes.ENTIRE_SCRIPT,
    "Sort Paragraphs"
);

Just for interest: this shows example of the padded numbers paragraphs that script uses to sort:
