The only suggestion is the use of @ that is not part of OSC specification and if the software use @ for his propel purpose it doesn't send it via osc.
This is the case for Reaper, here is an extract from their default file:
# ----------------------------------------------------------------
# OSC is a protocol for sending information between musical devices, over a network.
# Unlike MIDI, which is defined as a stream of bytes with specific meanings, OSC
# messages are human-readable text strings with no predefined meanings. It is
# entirely up to individual musical devices to define what specific messages mean and
# when those messages are sent.
# For two devices to work together (such as REAPER an and OSC control surface
# device), the user must configure one or both devices to send and receive messages
# that have meaning for the other device. This pattern config file is how REAPER
# defines the messages it understands. In order to use REAPER with an OSC device,
# you can either create a custom pattern config file so that REAPER sends and
# receives messages the OSC device understands, or configure the OSC device to send
# and receive messages that REAPER understands, or both.
# For basic information about OSC, see
http://opensoundcontrol.org/introduction-osc .
# Each line below is an action description in all caps, followed by a number of OSC
# message patterns. You can add, remove, or change patterns, delete lines, or comment
# out lines by adding '#', but do not change the action descriptions.
# The patterns following the action are the messages that REAPER will send and receive
# to and from the OSC device. An action can have no patterns (and will be ignored),
# one pattern, or many patterns.
# The patterns may contain the wildcard character '@'. (This is REAPER-only, not part
# of the OSC specification.) The '@' wildcard is used to specify the action target.
# ----------------------------------------------------------------
Perhaps Axel can clarify the reason why Lemur use '@' to send text to object, but what i see now, is "confusion" between different software.
For general information, i have found the script on Jazzmutant Forum with the same problem exposed

Anyway we have a working solution ....
