%reset is not parallel specific. 

>>> %reset?

Type:       Magic function
String Form:<bound method NamespaceMagics.reset of <IPython.core.magics.namespace.NamespaceMagics object at 0x101cb4950>>
Namespace:  IPython internal
File:       IPython/core/magics/namespace.py
Definition: %reset(self, parameter_s='')
Docstring:
Resets the namespace by removing all names defined by the user, if
called without arguments, or by removing some types of objects, such
as everything currently in IPython's In[] and Out[] containers (see
the parameters for details).
...

Yes it works from script if they are called script.ipy
or if you use the transformed form :

>>> get_ipython().magic(u'hist -t')
