I've found you have to have two separate sets of searches. Those you set up on the main website show in your saved searches for the mobile site but don't always work. The ones you set up on the mobile site aren't included in your list on the main site.
The mobile search is different and doesn't have all the same options as the main website - it's far more limited, so the tourers option I don't believe exists on the mobile version, nor does all the same sorting options.
