Tengo la siguiente estructura de matriz:

Array
        (
            [0] => Array
                (
                    [configuration_id] => 10
                    [id] => 1
                    [optionNumber] => 3
                    [optionActive] => 1
                    [lastUpdated] => 2010-03-17 15:44:12
                )

            [1] => Array
                (
                    [configuration_id] => 9
                    [id] => 1
                    [optionNumber] => 2
                    [optionActive] => 1
                    [lastUpdated] => 2010-03-17 15:44:12
                )

            [2] => Array
                (
                    [configuration_id] => 8
                    [id] => 1
                    [optionNumber] => 1
                    [optionActive] => 1
                    [lastUpdated] => 2010-03-17 15:44:12
                )
    )

¿Cuál es la mejor manera de ordenar la matriz, de forma incremental en función de la opción Número?

Entonces los resultados se ven así:

Array
        (
            [0] => Array
                (
                    [configuration_id] => 8
                    [id] => 1
                    [optionNumber] => 1
                    [optionActive] => 1
                    [lastUpdated] => 2010-03-17 15:44:12
                )

            [1] => Array
                (
                    [configuration_id] => 9
                    [id] => 1
                    [optionNumber] => 2
                    [optionActive] => 1
                    [lastUpdated] => 2010-03-17 15:44:12
                )

            [2] => Array
                (
                    [configuration_id] => 10
                    [id] => 1
                    [optionNumber] => 3
                    [optionActive] => 1
                    [lastUpdated] => 2010-03-17 15:44:12
                )
    )
