Cleaned up version of code posted at https://forum.sublimetext.com/t/run-multiple-commands-command/6848/35. Added support for repeated commands and example key mappings to move/scroll by ten lines.

run_multiple_commands.py

# run_multiple_commands.py
import sublime, sublime_plugin
# Takes an array of commands (same as those you'd provide to a key binding) with
# an optional context (defaults to view commands) & runs each command in order.
# Valid contexts are 'text', 'window', and 'app' for running a TextCommand,
# WindowCommands, or ApplicationCommand respectively.
class RunMultipleCommandsCommand(sublime_plugin.TextCommand):
	def exec_command(self, command):
		if not 'command' in command:
			raise Exception('No command name provided.')
		args = None
		if 'args' in command:
			args = command['args']

		if 'repeat' in command:
			repeat = command['repeat']
		else:
			repeat = 1

		# default context is the view since it's easiest to get the other contexts
		# from the view
		context = self.view
		if 'context' in command:
			context_name = command['context']

				context = context.window()

			if args is None:
				context.run_command(command['command'])
			else:
				context.run_command(command['command'], args)

	def run(self, edit, commands = None):

This doesn't seem to be working for me. I copied the py file and created it where it's supposed to be.
But my keymaps don't seem to work: (one is for cancelling gulp and the other for cancelling a build, I'd just like to run both since I only have one or the other running, never at the same time but want the same key command for both)

 {
    "keys": ["ctrl+c"],
    "command": "run_multiple_commands",
    "args":
    {
      "commands":
      [
        {"command": "gulp_kill", "args": { "silent": false }},
        {"command": "exec", "args": { "kill": true }}
      ]
    }
  },

I ended up figuring out that these commands required a context (either "window", "app", "text"). If unset, it uses the view as the context which doesn't necessarily handle these sorts of commands.

Fixed below:

  {
    "keys": ["ctrl+c"],
    "command": "run_multiple_commands",
    "args":
    {
      "commands":
      [
        {
          "command": "gulp_kill",
          "context": "window",
          "args": { "silent": false }
        },
        {
          "command": "exec",
          "context": "window",
          "args": { "kill": true }
        }
      ]
    }
  },
