Hi,
You might have to use CAML to perform your query if you want to sort by more than 2 columns.
You could modify your view using SharePoint designer.
I've already done it in the past using a Content Query WebPart and the QueryOverride parameter.
<OrderBy> <FieldRef Name="Newcomers"/> <FieldRef Name="Years" Ascending="FALSE"/> <FieldRef Name="Location"/> </OrderBy>

1) add one hidden column
2) concatenate 6 columns' value into the hidden column
3) sort the hidden column
