Distribute command-line arguments using npm as a build tool - node.js

Question

I have an npm package that manages my github repository and has scripts that build my publishable npm package. Due to the nature of the package, the published npm package (the distribution) cannot match my repository's package (the source). I am moving closer to test-driven development and continuous integration, but am learning it step-by-step. Here is the current flow and it works flawlessly, so far:
From the command line:
> npm run patch
runs npm version patch
This invokes source's preversion,
cleans the distro: npm run clean
runs the tests: npm test
This invokes pretest,
npm run build
Runs distro's tests
Failure: Errors and process ends
Success: Branch complete,
invokes the source's postversion:
git push all commits and tags
runs distro's npm version patch
invokes distro's postversion
npm publish
(Source) package.json
{
...,
"scripts": {
"patch": "npm version patch && cd dist && npm version patch",
"minor": "npm version minor && cd dist && npm version minor",
"major": "npm version major && cd dist && npm version major",
"preversion": "npm run clean && npm test",
"clean": /* clean commands */,
"pretest": "npm run build",
"test": "cd dist && npm test",
"postversion": "git push origin --all && git push origin --tags"
},
...
}
(Distro) package.json
{
...,
"scripts": {
"test": /* test commands */,
"postversion": "npm publish"
},
...
}
I would like to have a simpler interface. As you can see, I have to npm run <major|minor|patch>. I would instead like to npm run dist with a commandline arg passed to both npm versions.
Example:
> npm run dist patch
--------------------
<<< npm version patch
<<< cd dist && npm version patch
> npm run dist major
--------------------
<<< npm version major
<<< cd dist && npm version major
Is it possible to pass commandline args down the tree? Or, better yet, can I distribute a commandline arg across commands in a single scripts entry? I can easily add an entry to scripts that accepts a commandline argument, but cannot seem to figure out how to share that argument more than once with writing a separate .js script.
