If you highlight the list and turn it into a table:
(2003)
- Table > Convert > Text to Table
- (for a separator, use a SPACE)
(2007)
- Insert > Table > Convert Text to Table
- (for a separator, use a SPACE)
You can then sort the table by column 2:
(2003)
- Highlight table
- Table > Sort
- Sort by > Column 2
(2007)
- Table Tools > Layout
- Sort
- Sort by > Column 2
Then, if needed, convert back to text.
