Numeric sorting compare function factory. Method get as parameters `sortOrder` and `columnMeta` and return compare function.

@param {String} sortOrder Sort order (`asc` for ascending, `desc` for descending).
@param {Object} columnMeta Column meta object.
@param {Object} columnPluginSettings Plugin settings for the column.
@returns {Function} The compare function.
