Off the top of my head: digits have a mathcode "7000+x where x is their
value. This makes them come (in math mode) from the roman font.
If you set

\mathcode`0=7130 % 7100+ascii(0)
...
\mathcode`9=7139 % 7100+ascii(9)

then in math they should be from the italic font, which has the
old style digits.

In text mode there is no simple way to do this, other than
to make all them digits into active characters:

\catcode`0=13 \def0{{\textfont1 0}}
...
\catcode`9=13 \def9{{\textfont1 9}}

(these definitions are obviously incorrect, but I don't encourage
this approach anyhow.)

It looked pretty purrfect to me.
