I would think it will always match 1! because of the urgent priority setting.   Keep in mind the example you gave from the SRND list three different translation patterns.  The two you have are the same as far as the first two digits, no?

Assuming a user dials 1311 and we have patterns 1XXX, 1[2-3]XX, and 13!, the following table shows the number of matched strings of these potentially matching patterns....In this example the variable-length pattern 13! is selected as the best match.
