Use semi-colons between items in a list that already involve commas.
- I have lived in Chicago, Illinois; Kansas City, Missouri; and Omaha,
- The sweaters I bought today were purple, blue, and green;
yellow, white, and red; and pink, black, and grey.
From the APA Style Blog:
This gets more complex when an item or multiple items in
your list already have commas. In these cases, separate the items with
Each child was seated at a separate station and given the following
plush toy or toys: an elephant, which all children saw in the previous
experiment; a kangaroo, which only half of the children saw in the
previous experiment; or both the elephant and the kangaroo.
From these examples, it appears that your usage of semicolons to delimit a list that includes commas is correct.
If you are specifically referring to the usage of numbers within (although your sentence looks fine regardless), see this question.
Edit: I also found an MLA resource here (look for the parts on semicolons).
