TINYINT(2) UNSIGNED still has the normal range of values (0-255) of plain jane TINYINT UNSIGNED. The (2) is only a padding value if the column is declared with ZEROFILL.

To put clearer, if you try to insert a value of 100 into a TINYINT(2) column then it'll work fine. If you try to insert 256, then MySQL will throw back a warning "Out of range value adjusted for column 'id' at row 1" and adjust the value to 255.
