When annotating a column, how is one supposed to indicate in what
position the column is?

In the the spec [1], I see that "number" is a possible property for a
column. But in the csvw @context file [2], "number" resolves to
xsd:double, that is a datatype and not a property.

The spec, in the same section, also mentions a "source number", that
sounds like a useful property. But I can't find it in the csvw @context [2].

My experiments lead to the conclusion that the order in which the
columns are described in the schema implicitly determines their order in
the source table. If so, what are the properties mentioned in the spec for?
