Unable to run babel-node on Windows

I would appreciate it if someone could help me figure out what is causing the error mentioned below.

I have a test Express project with a scripts section in package.json that looks like the following:

"scripts": {
   "dev": "backpack",
   "build": "backpack build",
   "test-server": "babel-node node_modules/.bin/babel-istanbul cover node_modules/.bin/_mocha",
   "test-server-ms": "babel-node.cmd node_modules/.bin/babel-istanbul.cmd cover node_modules/.bin/_mocha.cmd"
},

The test-server-ms script is what I am trying to execute:

babel-node.cmd node_modules/.bin/babel-istanbul.cmd cover 
      node_modules/.bin/_mocha.cmd "test/server"

This yields an error when parsing the babel-istanbul.cmd file:

(function (exports, require, module, __filename, __dirname) { @IF EXIST "%~dp0\node.exe" (
                                                              ^
SyntaxError: Invalid or unexpected token

    at Object.require.extensions.(anonymous function) [as .js] (C:\Users\hqrsingh\Development\workspaces\vscode\express-es6-starter\node_modules\babel
-register\lib\node.js:152:7)
    at Module.load (module.js:487:32)
    at tryModuleLoad (module.js:446:12)

    at Object.<anonymous> (C:\Users\hqrsingh\Development\workspaces\vscode\express-es6-starter\node_modules\babel-cli\lib\_babel-node.js:154:22)

The error occurs when the @IF directive is encountered which is part of a Windows .cmd script in node_modules\.bin\babel-istanbul.cmd:

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe"  "%~dp0\..\babel-istanbul\lib\cli.js" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node  "%~dp0\..\babel-istanbul\lib\cli.js" %*
)

I am kicking all of this off within a Windows 7 Pro command shell via npm:

 npm run-script test-server-ms test/server

For reference, here is the entire package.json file:
