You might try using a callback function:

function getval( callback ){
    jQuery.getJSON('http://data.mtgox.com/api/1/BTCUSD/ticker?callback=?', function(data) {
        // We can't use .return because return is a JavaScript keyword.
        callback(data['return'].avg.value);
    });
}

$(function () {
        $(document).ready(function() {
        getval( function ( value ) { alert( 'Do something with ' + value + ' here!' ) } );
    });

});
