Hi all,
I had the following problem while using lsort
$ tclsh
>info pa
8.5.8
>set allelems [list [list chr12 5] [list chr04 1] [list chr08 13]]
{chr12 5} {chr04 1} {chr08 13}
>lsort -decreasing -index 1 $allelems
{chr12 5} {chr08 13} {chr04 1}
<-- !!!!
>lsort -decreasing -integer -index 1 $allelems
{chr08 13} {chr12 5} {chr04 1}

As you can see, I solved my problems by including the -integer option,
but why does lsort in its default setting consider 5 > 13 ?

Because its default setting is simply to sort everything as
strings. "5" comes after "13" just as "E" comes after "AC".

Because default is lexical ordering, and in a lexicon the word
"zoo" comes after "arena", no matter that "zoo" is shorter.

Thanks All!
Somehow I had the idea that it would be sorted as integers if only
integers were present.

Hmmm that confirms my suspicion... tip 131 is still not implemented!
maybe I should have tried
expr [rmmadwim([lsort $allelems])]
to see if I got what I wanted... ;-)

Cheers,
Cristian.

From the lsort man page:
By default ASCII sorting is used with the result returned in
increasing order. However, any of the following options may
be specified before list to control the sorting process
(unique abbreviations are accepted):
